Нейрофизиологические механизмы реализации немедикаментозной релаксации

Abstract

Проводилась регистрация биоэлектрической активности головного мозга в нервной, дыхательной и сердечнососудистой системах в процессе адаптивного биоуправления с биологической обратной связью и медитации. Выполнялась регистрация сверхмедленной нервной и сердечно-сосудистой деятельности в диапазоне от 0,07 до 1 Гц. К записям применялись узкополосные фильтры, включавшие альфа, бетаи тета-диапазоны. Решалась обратная задача ЭЭГ за счет локализации источников биоэлектрической активности мозга в исследуемых диапазонах (с использованием программы BrainLoc 6.0). Установлено участие различных структур мозга в реализации поведенческих стратегий в группах обучившихся различным видам самоуправления. Полученные результаты свидетельствуют, что механизм биологической обратной связи включает синхронизацию частоты дыхания, электрической активности головного мозга, сердечных сокращений и сосудистого тонуса. Происходит увеличение активности в вовлеченных в резонансный ответ структурах (ядра таламуса, сосудодвигательного и дыхательного центров).

Cerebral activity and infraslow activity in the nervous, respiratory and circulatory systems during biofeedback of cerebral hemodynamic parameters and meditation were studied. Infraslow nervous and cardiovascular activity was registered within a range between 0,07 and 1 Hz. Each EEG record was filtrated in the alpha 1-3, beta and theta bands. The inverse EEG problem was solved by localizing the sources of brain activity in filtering ranges (BrainLoc v.6.0 was used). We revealed an involvement of different brain structures in the implementation of behavioral strategies in different types of groups trained to self-government, suggesting different mechanisms to achieve the final result. The results suggest that the mechanism of biofeedback including synchronization of the respiratory rate, brain activity, heart rate and vascular tone frequencies. This resulted in an increased activity in the involved resonant response structures (thalamic pacemaker structures, vasomotor nuclei and respiratory centers).
