Even a Little Alcohol Can Harm Your Health
Recent research makes it clear that any amount of drinking can be detrimental. Here’s why you may want to cut down on your consumption beyond Dry January.

“Non-invasive” brain stimulation is not non-invasive
IntroductionThe functions of the healthy brain can be studied in two main ways. Firstly, the changes in the brain’s state can be measured using techniques such as EEG or functional MRI. Secondly, the activity of the brain can be disrupted through the use…

Clinical trials show encouraging safety profile for brain-computer interface turning thoughts into action
In an important step toward a medical technology that could help restore independence of people with paralysis, researchers find the investigational BrainGate neural interface system has low rates of associated adverse events.

Massive review study suggests psychological trauma nearly triples a person’s risk of mental disorder
A systematic review of 14 meta-analyses found strong evidence that psychological trauma increases one’s risk of mental disorder by nearly three-fold. The findings were published in the European Archives of Psychiatry and Clinical Neuroscience. ...

Deep brain stimulation in Early Onset Parkinson's disease

Глянул на abstract этой статьи: "Results: From 2004 - 2021, fourteen adults enrolled in the BrainGate trial had devices surgically implanted. The average duration of device implantation was 872 days, yielding 12,203 days of safety experience. There were 68 device-related adverse events, including 6 device-related serious adverse events. The most common device-related adverse event was skin irritation around the percutaneous pedestal. There were no safety events that required device explantation, no unanticipated adverse device events, no intracranial infections, and no participant deaths or adverse events resulting in permanently increased disability related to the investigational device."

The Brain Uses Calculus to Control Fast Movements
Researchers discover that to sharpen its control over precise maneuvers, the brain uses comparisons between control signals — not the signals themselves.
Приятно видеть, что здесь они ссылаются на Павлова. С другой стороны, весьма подозрительно, что в abstract'е не сказано, каким таким магическим способом они определяли присутствие mind-wandering по ЭЭГ. В таких случаях встает вопрос: если авторы не сумели изложить, что они сделали, в аннотации, стоит ли читать это литературное mind-wandering дальше? https://www.sciencedirect.com/science/article/pii/S0893608022004658?via%3Dihub

"The present results support the existence of a widespread, stable iEEG network, salient at both very high and very low frequencies through different phases of focal epilepsy, from interictal to preictal, and extending close to the edge of the visible seizure onset." In my humble opinion, это утверждение отличается от обычных разговорах о локализованных эпилептических очагах. http://www.physics.gsu.edu/dhamala/publications/Ghimire+Epstein+Dhamala_JCN2022.pdf
Все реже и реже попадаются статьи, в которых the Utah array записывает активность отдельных нейронов, но, вот, статьи с записью локальных потенциалов учащаются. В этой статье данная методика использовалась для выявления кортикальных волн, которые несли информацию о движении. Я тоже сторонник волн; они понятнее, чем "rotational dynamics". https://www.pnas.org/doi/10.1073/pnas.2212227120
