Nameless in anatomy, but famous among surgeons: The so called "deltotrapezoid fascia".

Acute dislocation of the acromioclavicular joint (AC-joint) often leads to disruption of the "deltotrapezoid fascia", a common aponeurosis of the deltoid and the trapezoid muscles. Various studies demonstrated that its reconstruction is crucial for functional recovery. Textbooks of anatomy, however, fail to mention this prominent structure that is also not listed in the Terminologia Anatomica provided by the Federative Committee on Anatomical Terminology (FCAT). Here, we demonstrate that the delta-trapezoid fascia is hardly visible in formalin-fixed, but prominent in fresh specimen. We provide an extensive anatomical description based on 11 specimens derived from eight body donators and show, as a major finding that different fixations massively impact on the structural integrity of the DTF. We hypothesize that modern (minimal-invasive) surgical strategies unraveled many structures of fundamental function that are not known by anatomists and therefore not covered by anatomical education.

A mind-brain-body dataset of MRI, EEG, cognition, emotion, and peripheral physiology in young and old adults.

We present a publicly available dataset of 227 healthy participants comprising a young (N=153, 25.1±3.1 years, range 20-35 years, 45 female) and an elderly group (N=74, 67.6±4.7 years, range 59-77 years, 37 female) acquired cross-sectionally in Leipzig, Germany, between 2013 and 2015 to study mind-body-emotion interactions. During a two-day assessment, participants completed MRI at 3 Tesla (resting-state fMRI, quantitative T1 (MP2RAGE), T2-weighted, FLAIR, SWI/QSM, DWI) and a 62-channel EEG experiment at rest. During task-free resting-state fMRI, cardiovascular measures (blood pressure, heart rate, pulse, respiration) were continuously acquired. Anthropometrics, blood samples, and urine drug tests were obtained. Psychiatric symptoms were identified with Standardized Clinical Interview for DSM IV (SCID-I), Hamilton Depression Scale, and Borderline Symptoms List. Psychological assessment comprised 6 cognitive tests as well as 21 questionnaires related to emotional behavior, personality traits and tendencies, eating behavior, and addictive behavior. We provide information on study design, methods, and details of the data. This dataset is part of the larger MPI Leipzig Mind-Brain-Body database.
