Cronología de la investigación sobre la dinámica cerebral de Justo Gonzalo / Chronology of Justo Gonzalo’s research on brain dynamics

Introducción: El neurocientífico español Justo Gonzalo y Rodríguez-Leal (1910-1986) investiga la organización funcional de la corteza cerebral durante más de cuatro décadas. Sus hallazgos le llevan a formular una teoría neurofisiológica basada en las leyes de la excitabilidad nerviosa, que denomina dinámica cerebral. En el presente trabajo se expone de forma cronológica cómo surgen las principales ideas sobre las que se articula.Desarrollo: En 1939 Gonzalo observa los denominados fenómenos de acción dinámica: desfasamiento, facilitación y repercusión cerebral. Le siguen dos principios: efecto cerebral de la lesión según la magnitud y posición (1941), y organización sensorial, según un desarrollo espiral (1947). Paralelamente, caracteriza lo que llama el síndrome central de la corteza cerebral. En la década de los cincuenta desarrolla los conceptos de gradiente cortical, similitud y alometría. En contraposición a las concepciones modulares de la corteza cerebral, en las que una región es responsable de una función, Gonzalo expresa que ‘los gradientes corticales dan la localización de los sistemas mientras la similitud y alometría revelan su trama funcional’.Conclusiones: La teoría de dinámica cerebral se articula en dos etapas. La primera (de 1938 a 1950) se caracteriza por una importante base clínica con observación de nuevos fenómenos y formulación de nuevos conceptos. La segunda (de 1950 a 1960) incluye la introducción de conceptos de mayor alcance, como el gradiente funcional cortical, y leyes de alometría que se basan en un cambio de escala. Actualmente, varios autores consideran que el concepto de gradiente es clave para entender la organización cerebral.(AU)

Introduction: The Spanish neuroscientist Justo Gonzalo y Rodríguez-Leal (1910-1986) investigated the functional organisation of the cerebral cortex over more than four decades. His findings led him to formulate a neurophysiological theory based on the laws of nervous excitability, which he called brain dynamics. This paper presents in chronological order how the main ideas on which it is based arose.Development: In 1939, Gonzalo observed the phenomena of dynamic action: asynchrony or disaggregation, facilitation and cerebral repercussion. This was followed by two principles: the cerebral effect of lesions according to their magnitude and position (1941), and spiral development of the sensory field (1947). At the same time, he characterised what he called the central syndrome of the cerebral cortex. In the 1950s he developed the concepts of the cortical gradient, similarity and allometry. In contrast to modular conceptions of the cerebral cortex, in which one region is responsible for one function, Gonzalo argued that ‘cortical gradients provide the location of systems, while similarity and allometry reveal their functional mechanism.’Conclusions: The theory of brain dynamics was established in two stages. The first (between 1938 and 1950) had an important clinical foundation, involving the observation of new phenomena and the formulation of new concepts. The second (between 1950 and 1960) included the introduction of more far-reaching concepts, such as the functional cortical gradient, and allometry laws based on a change of scale. Today, various authors believe that the concept of the gradient is crucial for understanding how the brain is organised.(AU)

Psychiatry and Decolonization: Histories of Transcultural Psychiatry in the Twentieth Century.

This review essay explores recent historical and anthropological literature on the emergence and development of transcultural psychiatry in the second half of the twentieth century. It examines how postcolonial psychiatry attempted to remove itself from its erstwhile colonial frameworks and strove to introduce new concepts and paradigms to make itself relevant in the context of decolonization and postwar reconstruction. The essay looks at both continuities and discontinuities between colonial and post-colonial transcultural psychiatry, asking how the recent surge of scholarly literature in this field engaged with these issues. It also aims to identify the most important avenues for future research.

[The birthing chair, obstetric bed and gynecological chair in obstetrics and gynecology in Russia of XVIII-XX centuries].

The purpose of the study is to investigate material culture of obstetrics in New and Modern history of Russia. The most important objective of research is to involve into scientific circulation Russian empirical material in order to study transformation of culture of childbirth during transition from traditional to biomedical model of childbirth exemplified by material culture items (maternity beds, chairs, armchairs). The key approaches were those of historical anthropology, social history of medicine, theory of social control and medicalization. The methods of content analysis, narrative and interpretive analysis were applied to analyze empirical data. In the Russian folk tradition included no such special devices as maternity beds and birth chairs that was explained by dominance of vertical maternity pose. The first birth chairs were brought into Russia by foreign midwives. With development of clinical obstetrics horizontal position of woman in labor was approving that was conditioned by convenience of physicians. Since last quarter of the XIX century, Russian physicians began to experiment, inventing most convenient version of maternity beds and gynecological chairs. The Soviet system of obstetrics was mass and publicly accessible, but consolidated technocratic model of childbirth. In maternity wards, the "Rakhmanov obstetric bed" became widespread. The chairs were not used during childbirth, being used exclusively in gynecology. The material culture of Soviet maternity hospitals turned out to be extremely stable and conservative. In modern Russian obstetrics, with transition to holistic model of childbirth and actualization of free positioning of woman in labor, transformer beds and fitballs began to be applied to provide optimal course of birth process. The material culture of obstetrics is closely related to dominant type of maternity culture.

[The review of the monograph "Ambroise Paré. The first surgeon of the Kingdom" by E. E. Berger].

The review considers the approach placing famous French surgeon A. Paré into more general European context of European Renaissance of XVI century and into local context of intellectual life of Paris of this period. The refutation of widespread in history of medicine opinion about strict separation of university medicine from artisan surgery in Medieval Europe is discussed.

[The Russian priority of development of intravenous anesthesia (Report I).]

The article analyses research activities of the discoverers of "Russian narcosis" from the Military Medical Academy of St. Petersburg: the head of the Department of Pharmacology N. P. Kravkov, the head of the Department of Hospital Surgery S. P. Fedorov and his resident A. P. Eremich. They for the first time in the world developed ideas of comprehensive experimental substantiation and then safe clinical administration of preparation "hedonal" to achieve stage of safe general anesthesia and implementation of long-term and traumatic operations. The scientific works of Russian discoverers indicated fundamentally new direction in formation of anesthesiology in the Russian Empire and in the world. A. P. Eremich at stage of preparatory tests, working out technique of intravenous infusion, determination of range of safe therapeutic doses and creation of special installation facilitating work with hedonal during operations of Professor S. P. Fedorov, can be recognized as the first Russian anesthesiologist and also as the first National resuscitator.

Ontological Psychoanalysis in Clinical Practice.

The author describes and then clinically illustrates what he terms the ontological dimension of psychoanalysis (having to do with coming into being) and the epistemological dimension of psychoanalysis (having to do with coming to know and understand). Neither of these dimensions of psychoanalysis exists in pure form; they are inextricably intertwined. Epistemological psychoanalysis, for which Freud and Klein are the principal architects, involves the work of arriving at understandings of play, dreams, and associations; while ontological psychoanalysis, for which Winnicott and Bion are the principal architects, involves creating conditions in which the patient might become more fully alive and real to him- or herself. The author provides clinical illustrations of the ontological dimension of psychoanalysis in which the process of the patient's coming more fully into being is facilitated by the experiences in which the patient feels recognized for the individual he is and is becoming. This occurs in an analysis in which the analyst and patient invent a form of psychoanalysis that is uniquely their own.

An all-embracing science: The anthropological conception of Paolo Mantegazza.

This paper deals with the anthropological conception of the first modern Italian anthropologist, Paolo Mantegazza (1831-1910). We will begin by contextualizing the status of anthropology in Italy during the second half of the 19th century. Subsequently, we will delve into some of the inspirations that led the Italians to have such a multifaceted conception of the discipline. Next, we will outline the content of this approach and clarify the meaning of "omnicomprehensive science." From there, we will come to understand the reason for the variety of interests of the anthropologist, who aimed to study the human being in all aspects of life. We will then mention the moral objective present in his professional journey: through an understanding of the complexity of human life, the anthropologist wanted to contribute to the progress and well-being of society; in other words, to "living well."

Novel Variant and Known Mutation in 23S rRNA Gene of Mycoplasma pneumoniae, Northern Vietnam, 2023.

During a 2023 outbreak of Mycoplasma pneumoniae-associated community-acquired pneumonia among children in northern Vietnam, we analyzed M. pneumoniae isolated from nasopharyngeal samples. In almost half (6 of 13) of samples tested, we found known A2063G mutations (macrolide resistance) and a novel C2353T variant on the 23S rRNA gene.

Psychobiographical reflections on Viktor von Weizsäcker within the cultural framework of salutogenesis and medical anthropology.

This article explores the life of Viktor von Weizsäcker (VvW, 1886-1957), a German medical doctor, philosopher and founder of the Heidelberg School of Anthropological Medicine, from a psychobiographical and salutogenic perspective. The authors use salutogenesis and sense of coherence (SOC), and take crucial cultural, historical, and socio-structural frameworks into account to explore the life during the 19th and 20th Centuries in Germany. They present the exploration of a strong SOC in the life of VvW and show how SOC is created within the tight family bonds of the family clan, which has produced many extraordinary theologists, philosophers, scientists and politicians over six generations. In a complex, interconnected and holistic way, SOC is evident in von VvW's individual life, and is also shown to be a family resource. This article contributes to psychobiography in three ways: it develops the salutogenetic perspective in psychobiography, explores the life of VvW within a specific sociocultural context, and investigates the life from a salutogenetic and socio-cultural perspective. Finally, conclusions are drawn, and recommendations for theory and practice are given.

The art of resilience: a psychobiography of Frida Kahlo.

This psychobiography of Frida Kahlo explores the psychology of the famous Mexican artist. Drawing upon Kahlo's paintings and diary entries, a rich psychological analysis of the feminist icon is juxtaposed with the zeitgeist of 20th century Mexico. Framed through the theoretical model of feminist psychology, Kahlo's role in promoting gender equality and dismantling patriarchal society is discussed. Physical pain resulting from illness and impalement by a metal pole in a trolley accident was matched, if not exceeded, by the psychological pain the artist felt due to resulting issues with fertility and the long-sought but never-realized role of motherhood, infidelity within her marriage, and the eventual loss of her ability to paint. Nevertheless, Kahlo's perseverance and strength led to worldwide recognition of her bold and vibrant paintings, vulnerably depicting her rich inner world. The present study utilises perspectives from art therapy and attachment theory to elucidate the factors contributing to Frida Kahlo's resilience in the face of lifelong trauma and chronic pain. Ultimately, Kahlo's life and work offer valuable insight into the psychological experiences of women in patriarchal societies, emphasising the importance of feminist perspectives in psychological research and highlighting the healing and resilience-promoting role of art.

The psychoanalytic setting: José Bleger's encuadre.

José Bleger's paper on the setting (encuadre) is integral to his 1967 book Symbiosis and Ambiguity. Relevant concepts from the book are summarised before examining his view of the setting as a "non-process" consisting of "constants", complementing the "variables" of the analytic process. Process and setting are related as figure and ground in Gestalt psychology. The ideally maintained setting is studied as a thought experiment, uniting the categories of institution, personality, body schema, and body. Deposited in the setting, the psychotic part of the personality, or "agglutinated nucleus", is a remnant of early symbiosis with the mother. Bleger distinguishes two settings: the analyst's and the patient's. The latter can only be analysed by strictly maintaining the former. Ritualisation of the setting denies temporal reality. De-symbiotisation is not always possible. A concept of "internal" setting is suggested, but Bleger nowhere mentions this and the concept is problematic, leaving open the question of how to listen to the silence of the setting. Bleger's concept of encuadre can be applied to constants (invariants) in the wider world, the psychotic part of the personality being deposited in everything that is familiar and felt to be constant, including technology, which creates a "platform" for human activity.

On the question of the internal frame.

This paper attempts to expand José Bleger's classic, metapsychological descriptions of the psychoanalytic frame to formulate and emphasize the role of the analyst's internal frame in establishing a psychoanalytic observational perspective in the analytic situation. The rationale for doing so follows from clinical necessity, especially when working with patients and psychic organizations that are 'beyond neurosis' and in non-traditional settings such as distance and telemetric analyses. Clinically speaking, in its most effective state, the analyst's internal frame can inform the possibility of an observational vertex aimed at the intuitive grasp of psychic reality rather than a sense-based, empirical observation of parameters denoted by the elements of a consensually validatable social reality.

Freud's interpretation in "Medusa's Head" and some alternative psychoanalytic implications of Ovid's Medusa.

Freud's very brief 1922 paper on the beheading of Medusa by Perseus wisely concludes with a call for a further examination of the sources of the legend. A now widespread interpretation of this legend is based (often without acknowledgement) on an addition to traditions concerning Medusa made in Ovid's Metamorphoses. It is argued here that this Ovidian innovation has often been misinterpreted, and that a more careful reading of Metamorphoses supports neither a widely alleged exclusively vengeful portrayal of Medusa, nor Freud's portrayal of Medusa's decapitation as solely a pitiable and terrible symbol of castration. Instead, Ovid's complex treatments of myths involving Medusa, Minerva and Perseus present parallels with Kleinian insights into phantasy attacks on fecundity, and into imagined revivals of dead or damaged inside babies. Thus the "displacement upwards" of the fearful castrated maternal genital envisioned in Freud's "Medusa's Head" must stand beside a quite different "displacement upwards" of the life-giving maternal genital. Indeed, tradition holds that Medusa's beheading gives rise to the birth of vigorous twins. Together with allied details, this aligns Ovid's masterwork with theories that modify or displace the so-called "sexual phallic monism" that some believe taints Freud's theories of gender development.
