[Directed regulation of human alpha-rhythm using feedback].

Directed control of intensity of the alpha-rhythm in the somatosensory cortical regions was examined in 20 healthy subjects in conditions of combined (visual and auditory) feedback connection. An attempt has been made to single out by means of control experiments, the factors influencing in such conditions of external stimulation the brain bioelectrical activity. A study was made of the changes in effectiveness of biocontrol in multiple (five) sessions of training. Data are given on the dynamics of some vegetative functions in controlling brain biopotentials.
