RESUMEN

Wearable electroencephalography (EEG) and electrocardiography (ECG) devices may offer a non-invasive, user-friendly, and cost-effective approach for assessing well-being (WB) in real-world settings. However, challenges remain in dealing with signal artifacts (such as environmental noise and movements) and identifying robust biomarkers. We evaluated the feasibility of using portable hardware to identify potential EEG and heart-rate variability (HRV) correlates of WB. We collected simultaneous ultrashort (2-min) EEG and ECG data from 60 individuals in real-world settings using a wrist ECG electrode connected to a 4-channel wearable EEG headset. These data were processed, assessed for signal quality, and analyzed using the open-source EEGLAB BrainBeats plugin to extract several theory-driven metrics as potential correlates of WB. Namely, the individual alpha frequency (IAF), frontal and posterior alpha asymmetry, and signal entropy for EEG. SDNN, the low/high frequency (LF/HF) ratio, the Poincaré SD1/SD2 ratio, and signal entropy for HRV. We assessed potential associations between these features and the main WB dimensions (hedonic, eudaimonic, global, physical, and social) implementing a pairwise correlation approach, robust Spearman's correlations, and corrections for multiple comparisons. Only eight files showed poor signal quality and were excluded from the analysis. Eudaimonic (psychological) WB was positively correlated with SDNN and the LF/HF ratio. EEG posterior alpha asymmetry was positively correlated with Physical WB (i.e., sleep and pain levels). No relationships were found with the other metrics, or between EEG and HRV metrics. These physiological metrics enable a quick, objective assessment of well-being in real-world settings using scalable, user-friendly tools.

RESUMEN

The interplay between the brain and the cardiovascular systems is garnering increased attention for its potential to advance our understanding of human physiology and improve health outcomes. However, the multimodal analysis of these signals is challenging due to the lack of guidelines, standardized signal processing and statistical tools, graphical user interfaces (GUIs), and automation for processing large datasets or increasing reproducibility. A further void exists in standardized EEG and heart-rate variability (HRV) feature extraction methods, undermining clinical diagnostics or the robustness of machine learning (ML) models. In response to these limitations, we introduce the BrainBeats toolbox. Implemented as an open-source EEGLAB plugin, BrainBeats integrates three main protocols: 1) Heartbeat-evoked potentials (HEP) and oscillations (HEO) for assessing time-locked brain-heart interplay at the millisecond accuracy; 2) EEG and HRV feature extraction for examining associations/differences between various brain and heart metrics or for building robust feature-based ML models; 3) Automated extraction of heart artifacts from EEG signals to remove any potential cardiovascular contamination while conducting EEG analysis. We provide a step-by-step tutorial for applying these three methods to an open-source dataset containing simultaneous 64-channel EEG, ECG, and PPG signals. Users can easily fine-tune parameters to tailor their unique research needs using the graphical user interface (GUI) or the command line. BrainBeats should make brain-heart interplay research more accessible and reproducible.

RESUMEN

Introduction: Salivary alpha-amylase (sAA) is considered a marker of autonomic nervous system activity in stress research, and atypical waking sAA responses have been reported for traumatized individuals. Lucid dreams, characterized by a dreamer's awareness of their dream state while remaining asleep, have shown promising preliminary evidence of their potential to enhance mental health. This study's objective was to evaluate sAA in relation to healing lucid dreams. Methods: Participants experiencing PTSD symptoms attended a six-day workshop delivered via live video designed to teach techniques for transforming trauma through dreamwork and dream lucidity. Participants (n = 20) collected saliva samples each morning, immediately upon awakening (Time 1) and 30 min afterward (Time 2). sAA levels were determined by enzymatic assay, and the waking sAA slope was calculated as the difference of Time 2 minus Time 1. Participants completed dream reports each morning, with a dream classified as a 'healing lucid dream' when they reported attaining lucidity and remembered their intention to manifest a healing experience within the dreamscape. Results: Of eight participants experiencing healing lucid dreams, four were able to provide usable saliva samples. Statistical tests on these four participants were not significant because of low power. However, nonsignificant positive associations were observed between experiencing more healing lucid dreams and increased waking sAA slope. Conclusion: The results did not reveal a consistent effect of healing lucid dreams on waking sAA slope. Identifying meaningful patterns in this relationship will require larger samples and more stringent control over saliva collection procedures in future studies.

RESUMEN

Some people claim to occasionally know who is calling them without using traditional means. Controlled experiments testing these claims report mixed results. We conducted a cross-sectional study of triads examining the accuracy of knowing who was calling using two randomly selected designs: 1) a web server randomly chose the caller before the callee's guess (telepathic/pre-selected trials), and 2) a web server randomly chose the caller after the callee's guess (precognitive/post-selected trials). We also performed exploratory multilevel mixed-effects logistic regressions on the relationship of genetic relationships, emotional closeness, communication frequency, and physical distance data with accuracy. A total of 177 participants completed at least one trial (105 "completers" completed all 12 trials). Accuracy was significantly above chance for the 210 completers telepathic/pre-selected trials (50.0% where the chance expectation was 33.3%, p<.001) but not the 630 completers precognitive/post-selected trials (31.9% where the chance expectation was 33.3%, p = .61). We discuss how these results favor the psi hypothesis, although conventional explanations cannot be completely excluded. Genetic relatedness significantly predicted accuracy in the regression model (Wald χ2 = 53.0, P < .001) for all trials. Compared to 0% genetic relatedness, the odds of accurately identifying the caller was 2.88 times (188%) higher for 25% genetic relatedness (Grandparent/Grandchild or Aunt/Uncle or Niece/Nephew or Half Sibling; ß = 1.06, z = 2.10, P = .04), but the other genetic relatedness levels were not significant. In addition, communication frequency was significant (ß = 0.006, z = 2.19, P = .03) but physical distance (ß = 0.0002, z = 1.56, P = .12) and emotional closeness (ß = 0.005, z = 1.87, P = .06) were not for all trials. To facilitate study recruitment and completion, unavoidable changes to the protocol were made during the study due to persistent recruitment difficulties, including changing inclusion/exclusion criteria, increasing total call attempts to participants, adjusting trial type randomization schema to ensure trial type balance, and participant compensation. Thus, future research will be needed to continue to improve the methodology and examine the mechanism by which people claim to know who is calling, as well as factors that may moderate the effects.

RESUMEN

Trance is an altered state of consciousness characterized by alterations in cognition. In general, trance states induce mental silence (i.e., cognitive thought reduction), and mental silence can induce trance states. Conversely, mind-wandering is the mind's propensity to stray its attention away from the task at hand and toward content irrelevant to the current moment, and its main component is inner speech. Building on the previous literature on mental silence and trance states and incorporating inverse source reconstruction advances, the study's objectives were to evaluate differences between trance and mind-wandering states using: (1) electroencephalography (EEG) power spectra at the electrode level, (2) power spectra at the area level (source reconstructed signal), and (3) EEG functional connectivity between these areas (i.e., how they interact). The relationship between subjective trance depths ratings and whole-brain connectivity during trance was also evaluated. Spectral analyses revealed increased delta and theta power in the frontal region and increased gamma in the centro-parietal region during mind-wandering, whereas trance showed increased beta and gamma power in the frontal region. Power spectra at the area level and pairwise comparisons of the connectivity between these areas demonstrated no significant difference between the two states. However, subjective trance depth ratings were inversely correlated with whole-brain connectivity in all frequency bands (i.e., deeper trance is associated with less large-scale connectivity). Trance allows one to enter mentally silent states and explore their neurophenomenological processes. Limitations and future directions are discussed.

RESUMEN

CONTEXT: Many cultures believe that the first traces of human consciousness during the incarnation may be present before birth. Practices based on this belief exist in many cultures. However, formal scientific inquiry into the possibility of communicating with prenatal consciousness has never been explored. OBJECTIVE: To evaluate if it is possible to communicate with a hypothetical prenatal consciousness of the fetus during pregnancy. DESIGN: This exploratory study used mixed methods and a triple-blind design. People (i.e., mediums) who could allegedly communicate with eleven pregnant women's prenatal consciousness (N=11) collected answers to ten questions that were then verified from parental reports. Ten mediums participated, with three to eight mediums providing answers per pregnant woman. RESULTS: More than 1,500 statements were generated from attempts to communicate with the prenatal consciousness. Quantitative analysis showed higher agreement in spontaneously reported information versus responses to structured questions, 69.40%, and 17.63%, respectively. These results did not differ by the number of mediums per pregnant woman (three to five versus six to eight). Qualitative analysis suggested that some sessions resulted in verifiable communication with the prenatal consciousness, while others did not. CONCLUSION: The results, while preliminary and requiring follow-up studies, suggest the possibility to interact with a prenatal consciousness during pregnancy and the potential of novel scientific investigations into altered states of consciousness.

RESUMEN

The nature of consciousness is considered one of science's most perplexing and persistent mysteries. We all know the subjective experience of consciousness, but where does it arise? What is its purpose? What are its full capacities? The assumption within today's neuroscience is that all aspects of consciousness arise solely from interactions among neurons in the brain. However, the origin and mechanisms of qualia (i.e., subjective or phenomenological experience) are not understood. David Chalmers coined the term "the hard problem" to describe the difficulties in elucidating the origins of subjectivity from the point of view of reductive materialism. We propose that the hard problem arises because one or more assumptions within a materialistic worldview are either wrong or incomplete. If consciousness entails more than the activity of neurons, then we can contemplate new ways of thinking about the hard problem. This review examines phenomena that apparently contradict the notion that consciousness is exclusively dependent on brain activity, including phenomena where consciousness appears to extend beyond the physical brain and body in both space and time. The mechanisms underlying these "non-local" properties are vaguely suggestive of quantum entanglement in physics, but how such effects might manifest remains highly speculative. The existence of these non-local effects appears to support the proposal that post-materialistic models of consciousness may be required to break the conceptual impasse presented by the hard problem of consciousness.

RESUMEN

Noetic comes from the Greek word noesis, meaning inner wisdom or direct knowing. Noetic experiences often transcend the perception of our five senses and are ubiquitous worldwide, although no instrument exists to evaluate noetic characteristics both within and between individuals. We developed the Noetic Signature Inventory (NSI) through an iterative qualitative and statistical process as a tool to subjectively assess noetic characteristics. Study 1 developed and evaluated a 175-item NSI using 521 self-selected research participants, resulting in a 46-item NSI with an 11-factor model solution. Study 2 examined the 11-factor solution, construct validity, and test-retest reliability, resulting in a 44-item NSI with a 12-factor model solution. Study 3 confirmed the final 44-item NSI in a diverse population. The 12-factors were: (1) Inner Knowing, (2) Embodied Sensations, (3) Visualizing to Access or Affect, (4) Inner Knowing Through Touch, (5) Healing, (6) Knowing the Future, (7) Physical Sensations from Other People, (8) Knowing Yourself, (9) Knowing Other's Minds, (10) Apparent Communication with Non-physical Beings, (11) Knowing Through Dreams, and (12) Inner Voice. The NSI demonstrated internal consistency, convergent and divergent content validity, and test-retest reliability. The NSI can be used for the future studies to evaluate intra- and inter-individual variation of noetic experiences.

RESUMEN

OBJECTIVE: Human gene expression studies typically rely on peripheral blood samples as a cellular source, however there are numerous situations in which venipuncture is contraindicated. To this end, an oral rinse-based method for collecting salivary neutrophils as a cellular source for gene expression analyses was previously developed and shown in a pilot study with five male participants to yield mRNA expression results comparable to those obtained from peripheral blood samples. The objective of the current study was to characterize the generalizability of the oral rinse-based method by analyzing unpublished RNA quality data obtained through a parent study that collected salivary neutrophil samples using the method from a larger sample size and including both men and women. RESULTS: The 260/280 nm absorbance ratios of the RNA obtained from 48 participants using the oral rinse-based method were within the expected range (average = 1.88 ± 0.16) for the majority of the samples, and no significant differences in RNA quality were found between participants' health, age group, or gender. Together with published data confirming the integrity of RNA obtained using the same method, these results support the feasibility of using this noninvasive method for obtaining samples for human gene expression analyses.

RESUMEN

Introduction: Personal development workshops are increasingly popular. This study evaluated the relationships between the measures of well-being, interconnectedness, and extended perception in various workshops and explored which kinds of workshops and individual characteristics predicted changes in these outcomes. Materials and Methods: In a prospective, uncontrolled, within-participant design study, adult participants completed questionnaires and online tasks before and after personal development workshops. Three analyses were conducted: (1) examining the relationships between measures by using only pre-workshop measures using Spearman correlations; (2) exploring change scores pre- to post-workshop and workshop using Wilcoxon signed-rank test; (3) assessing workshop format and content, and individual characteristics as predictors of those change scores multivariate nonparametric regression. The following outcomes were collected: Well-being-Arizona Integrative Outcomes Scale, positive and negative affect, Dispositional Positive Emotions Scale-Compassion subscale, Sleep Quality Scale, Numeric Pain Rating Scale; Interconnectedness-Cloninger Self-Transcendence Scale, Inclusion of Nature in Self and Inclusion of the Other in Self; and Extended perception tasks-Intuition Jar, Quick Remote Viewing, Psychokinesis Bubble, and Time Estimation. The following potential predictor variables were collected: demographic, mental health, psychiatric and meditation history, Single General Self-Rated Health Question, Brief Five-Factor Inventory-10, and the Noetic Experience and Belief Scale. Workshop leaders also selected which format and content characteristics applied to their workshop. Results: Interconnectedness measures were significantly and positively correlated with well-being (ρ: 0.27 to 0.33), positive affect (ρ: 0.20 to 0.27), and compassion (ρ: 0.21 to 0.32), and they were negatively correlated with sleep disturbance (ρ: -0.13 to -0.16) and pain (ρ: -0.11 to -0.16). Extended perception task performance was not correlated with interconnectedness or well-being. General personal development workshops improved subjective interconnectedness, well-being, positive emotion, and compassion, and they reduced sleep disturbances, negative emotion, and pain (all p's < 0.00005). The lecture (p = 0.03), small groups (p = 0.001), pairs (p = 0.01), and discussion (p = 0.03) workshop formats were significant predictors of well-being outcomes. The workshop content categories of meditation (p = 0.0002) and technology tools (p = 0.01) were also predictive of well-being outcomes, with meditation being the most consistent predictor of positive well-being changes. Conscientiousness was the only significant individual characteristic predictor (p = 0.002), although it was associated with increases in some well-being measures and decreases in others. Conclusions: This study provides preliminary evidence for the positive relationship between the subjective sense of interconnectedness and multiple well-being measures and the beneficial effects of some personal development workshops.

RESUMEN

INTRODUCTION: It is commonly believed that psychic ability, like many mental and physical traits, runs in families. This suggests the presence of a genetic component. If such a component were found, it would constitute a biological marker of psychic ability and inform environmental or pharmacologic means of enhancing or suppressing this ability. METHODS: A case-control study design was used to evaluate differences between psychic cases and non-psychic controls. Over 3,000 candidates globally were screened through two online surveys to locate people who claimed they and other family members were psychic. Measures of relevance to the claimed abilities (e.g., absorption, empathy, schizotypy) were collected and based on those responses, individuals with indications of psychotic or delusional tendencies were excluded from further consideration. Eligible candidates were then interviewed and completed additional screening tests. Thirteen individuals were selected as the final "psychic cases," and ten age-, sex-, and ethnicity-matched individuals with no claims of psychic ability were selected as controls. DNA from the saliva of these 23 participants was subjected to whole-exome sequencing. Two independent bioinformatics analyses were blindly applied to the sequenced data, one focusing exclusively on protein-coding sequences and another that also included some adjacent noncoding sequences. RESULTS: Sequencing data were obtained for all samples, except for one in the control group that did not pass the quality controls and was not included in further analyses. After unblinding the datasets, none of the protein-coding sequences (i.e., exons) showed any variation that discriminated between cases and controls. However, a difference was observed in the intron (i.e., non-protein-coding region) adjacent to an exon in the TNRC18 gene (Trinucleotide Repeat-Containing Gene 18 Protein) on chromosome 7. This variation, an alteration of GG to GA, was found in 7 of 9 controls and was absent from all psychic cases. DISCUSSION: The most conservative interpretation of these results is that they result from random population sampling. However, when the results are considered in relation to other lines of evidence, the results are more provocative. Further research is justified to replicate and extend these findings.

RESUMEN

PTSD and depression represent major individual and societal burdens. Depression is commonly comorbid with PTSD among veterans, although buffers of this relationship are unclear. We evaluated whether facets of mindfulness moderated the relationship between PTSD and depression in veterans with PTSD (N = 70). Three facets - nonjudging, acting with awareness, and nonreactivity - were assessed as moderators. Results indicated nonreactivity significantly attenuated the relationship between PTSD and depression (p=.013), such that veterans with high nonreactivity (+1 SD) showed a nonsignificant relationship between PTSD and depression, whereas veterans with average (Mean; p<.001) and low (-1 SD; p<.001) nonreactivity exhibited a significant relationship.

RESUMEN

Channeling experiences are often compared with Dissociative Trance/Possession Disorders and Dissociative Identity Disorders and more recent diagnostic criteria presented in the DSM 5 and ICD-11. From this comparison, it emerges quite clearly that, for most cases, channeling can either be considered an exceptional non-ordinary mental experience or a non-pathological Dissociative Trance/Possession experience. If this characterization is valid, the next step is to understand the origin of channeling experiences. Are they an expression of channeler's unconscious or voluntary mental mechanisms, or real connections with "other discarnate entities"? Given their peculiar characteristics, channeling experiences offer a unique opportunity for a scientific investigation and in particular, the origin of the information received by the channelers.

RESUMEN

Purpose: We qualitatively evaluated breast cancer survivors' perception of the relation between breast cancer development and both childhood trauma and stressful life events in adulthood.Methods: Women (N = 50) who have or had a positive breast cancer diagnosis completed a close-ended survey, a timeline of significant life events, and an in-depth interview. All interviews were transcribed and inductively coded using thematic analysis with an emphasis on patient perspectives of illness.Results: Participants reported a perceived connection between breast cancer development and stressful life events, and four themes were identified: 1) experiencing major interpersonal stress in both childhood and adulthood, 2) ideas about the relationship between emotional stress and physical disease, 3) ideas about how different types of stress contribute to developing breast cancer, 4) post-treatment post-traumatic growth and meaning-making.Conclusions: Our findings suggest that of the participants who felt something could be causally attributed to their developing breast cancer, most of them made causal attributions between social, personal, and physical stress and trauma across the lifetime to the aetiology of their breast cancer. We suggest that breast cancer patients and survivors may benefit from additional psycho-social, stress-reducing, and/or somatic-based trauma-informed therapies to address stress and trauma.

RESUMEN

The term "noetic" comes from the Greek word noesis/noetikos that means inner wisdom, direct knowing, intuition, or implicit understanding. Strong cultural taboos exist about sharing these experiences. Thus, many may not feel comfortable transparently discussing or researching these topics, despite growing evidence that these experiences may be real. The study's objective was to qualitatively evaluate first-hand accounts of noetic experiences. 521 English-speaking adults from around the world completed an online survey that collected demographic data and four open-ended questions about noetic experiences. Thematic analysis was used to characterize the data. The ten most used codes were expressing to or sharing with others, impacting decision-making, intuition/"just knowing," meditation/hypnosis, inner visions, setting intentions/getting into the "state," healing others, writing for self, and inner voice. There were five main themes identified: 1. Ways of Engagement; 2. Ways of Knowing; 3. Types of Information; 4. Ways of Affecting; and 5. Ways of Expressing. Subthemes. Future research will include investigating the nuances of these themes and also establishing standardized methods for evaluating them. This would also then inform curricula and therapies to support people in these experiences.

RESUMEN

Electroencephalography (EEG) alpha asymmetry is thought to reflect crucial brain processes underlying executive control, motivation, and affect. It has been widely used in psychopathology and, more recently, in novel neuromodulation studies. However, inconsistencies remain in the field due to the lack of consensus in methodological approaches employed and the recurrent use of small samples. Wearable technologies ease the collection of large and diversified EEG datasets that better reflect the general population, allow longitudinal monitoring of individuals, and facilitate real-world experience sampling. We tested the feasibility of using a low-cost wearable headset to collect a relatively large EEG database (N = 230, 22-80 years old, 64.3% female), and an open-source automatic method to preprocess it. We then examined associations between well-being levels and the alpha center of gravity (CoG) as well as trait EEG asymmetries, in the frontal and temporoparietal (TP) areas. Robust linear regression models did not reveal an association between well-being and alpha (8-13 Hz) asymmetry in the frontal regions, nor with the CoG. However, well-being was associated with alpha asymmetry in the TP areas (i.e., corresponding to relatively less left than right TP cortical activity as well-being levels increased). This effect was driven by oscillatory activity in lower alpha frequencies (8-10.5 Hz), reinforcing the importance of dissociating sub-components of the alpha band when investigating alpha asymmetries. Age was correlated with both well-being and alpha asymmetry scores, but gender was not. Finally, EEG asymmetries in the other frequency bands were not associated with well-being, supporting the specific role of alpha asymmetries with the brain mechanisms underlying well-being levels. Interpretations, limitations, and recommendations for future studies are discussed. This paper presents novel methodological, experimental, and theoretical findings that help advance human neurophysiological monitoring techniques using wearable neurotechnologies and increase the feasibility of their implementation into real-world applications.

RESUMEN

INTRODUCTION: Some "energy medicine" modalities, such as Reiki, continue to show evidence for efficacy, but the underlying mechanisms of action are still uncertain. To help illuminate possible mechanisms, this exploratory mixed-method study using qualitative and quantitative analyses investigated: 1) How do energy medicine sessions function from the perspective of a seer, i.e., an individual trained in techniques to enable perception of purported subtle energies, and 2) Do any of these observations correlate with changes in participants' subjective pain? METHOD: One seer reported observations during 30-minute energy medicine sessions delivered by 17 practitioners to participants experiencing chronic hand or wrist pain. Data were coded using an inductive approach, followed by thematic and descriptive analyses. Content analysis was used to assign whether each code was mentioned by the seer for each participant, generating 119 binary variables, one for each code. The relationship between these binary variables and change in participant pain scores after the energy medicine session and three weeks later were explored using linear regression models. RESULTS: The qualitative thematic analysis identified six major themes from the seer's notes: "Experience of the Practitioner," "Experience of the Participant," "Space and Other Beings" (referring to the qualities of the physical space the energy medicine session occurred in and ostensible non-physical beings present during session), "Participant-Practitioner Relationship," "Healing Process," and "Attributes of Energy." The energy medicine methods used varied for each participant, according to the practitioners' perceptions of each individual's needs. The linear regression models yielded significant associations between changes in pain scores and various codes, including energy color, practitioner touch and the presence of ostensible non-physical beings supporting the session, although their significance did not persist after correction for multiple comparisons. DISCUSSION: Future studies investigating the mechanisms of energy medicine may benefit from including perceptions by seers in their outcome measures.

RESUMEN

Previously reported experiments suggest that healing intention focused toward water, or merely taking place in the vicinity of water, affects the hydrogen-oxygen (HO) covalent bonds. This claim was explored in the context of a clinical energy medicine pilot study involving 17 practitioners and 190 participants. In a "direct" test, samples of water were directly treated by the practitioners; in an "indirect" test, aliquots attached to lanyards were worn by practitioners and participants as they were engaged in healing sessions. Samples of laboratory-grade distilled water and Fiji brand water were used in the tests, and the water was analyzed using an Attenuated Total Reflection (ATR) Fourier Transform Infrared (FTIR) spectrometer equipped with a liquid nitrogen-cooled detector. The comparison of interest was the ensemble average spectrum recorded during pre- vs. post-intentional healing periods in the primary infrared absorption portion of the water spectrum. The analyses indicated that distilled water directly treated by the practitioners resulted in a change in the HO bond at the wavenumber 3200 cm-1 (p < 0.03, two-tailed). No effect was observed with the Fiji water. The distilled water in aliquots worn by practitioners also resulted in a significant change at the same wavenumber (p = 0.0004, two-tailed). No effects were observed in Fiji water aliquots worn by practitioners or participants, or in distilled water worn by participants. This study contributes to previously reported observations suggesting that the structure of water reacts in an anomalous way to healing intentions. Such effects appear to involve some form of energetic influence, but that is not yet well established. Nor is it certain that the observed effect can only be due to intention; it is conceivable, for example, that an unidentified environmental factor may have been responsible for the observed comparisons. However, given similar results observed in several experiments so far, including the present study, further research seems warranted.

RESUMEN

INTRODUCTION: Outcomes of medical treatments tend to be highly variable. Some of the underlying variance is due to well-known factors such as age, gender, ethnicity, and effects of local weather. There are also less obvious influences including variations in solar wind, the Earth's geomagnetic field, and the interplanetary magnetic field. This study explored possible effects of these local and solar/geomagnetic variables on the outcomes of energy medicine treatments. The context was a pilot clinical trial involving 17 energy medicine practitioners who treated a total of 190 participants presenting with hand and wrist pain. METHODS: Eighteen environmental variables were correlated against changes in subjective pain and against changes in objective measures of nerve conduction velocity. RESULTS: The results showed that local barometric pressure, interplanetary magnetic field, lunar illumination, proton fluence, electron fluence, and solar radio flux showed statistically significant relationships with these health outcomes (at p < 0.05 or better) before correction for multiple comparison corrections. The variable of barometric pressure had a robust correlation with nerve conduction velocity, surviving adjustment for false discovery rate among the 18 variables at p < 0.05. DISCUSSION: This study lends support for future research into local weather, and potentially also to fluctuations in the solar/geomagnetic environment environmental measures as potential sources of variation in energy medicine sessions.

RESUMEN

INTRODUCTION: Previously reported experiments suggest that aspects of the physical environment, in particular measures of negentropy (i.e., order) associated with the statistical outputs of truly random number generators, may be affected during periods of focused mental attention. The present study was designed to conceptually replicate those reports during energy medicine sessions. METHOD: A custom-built "quantum noise generator" (QNG) was used to continuously record and digitize (at 1 KHz) 16 independent channels of random samples (i.e., noise) produced by electron tunneling and avalanche effects in Zener diodes. One metric was developed to quantify temporal dependencies in the noise samples aggregated across the 16 channels, and a second metric was formed that measured spatial dependencies among the 16 channels. The two metrics were combined into a single "spacetime" variable used to measure fluctuations in entropy during 110 half-hour energy medicine sessions. As a control, the same measure was examined in data recorded eight hours after each energy medicine session took place, when no one was in the laboratory. RESULTS: QNG data recorded during the half-hour sessions showed significant deviations from chance expectation, with a peak deviation observed at 24 minutes into the half-hour (z = 4.24, p < 0.00003, two-tail), and with deviations associated with p < 0.05 from 20 to 29 min, after correction for multiple comparisons. By comparison, data recorded eight hours after each session showed uniformly null results. This outcome is consistent with previously reported studies, suggesting that during periods of focused attention negentropic deviations emerge in random physical systems. Counterarguments to this interpretation are discussed, as well as recommendations for future studies.
