Scientists Create Open Dataset for Studying Concentration
A team of Russian researchers, including scientists from HSE University–St Petersburg, has developed the first open multimodal dataset containing recordings of brain activity, heart function, and video observations to help researchers understand what happens in the human brain during deep concentration. In the future, the dataset could accelerate the development of neural interfaces, rehabilitation technologies, and AI systems. The article has been published in Scientific Data.

Association between sleep patterns, somatization, and depressive symptoms among Russian university students

Chronobiology International. 2023. Vol. 40. No. 2. P. 215–221.
Dokuka S., Mikhaylova O., Krekhovets E.

In adolescents and young adults, physical and mental health are known to be associated with sleep. In this paper, we consider the connection between health indicators and sleep patterns. We collected and analyzed data of 267 master’s and bachelor’s degree students from 21 educational programs at one elite Russian university. Somatic health and mental health were measured using, respectively, the 8-item and the 15-item Patient Health Questionnaire, and sleep patterns were identified using the Munich Chronotype Questionnaire. The results indicated that shorter sleep time, later bedtime, and later rising time on workdays were associated with student somatic health. Shorter sleep on workdays was positively associated with the severity of depressive symptoms. Our findings highlight the importance of healthy sleep behavior for student health.
