[Electroencephalographic signs of internal attention in the mental counting of heart beats].
Attention is regarded as a dynamic spatio-temporal structure reflected inter alia in distribution patterns of total spectral power density of EEG alpha-rhythm obtained in volunteers. Factors influencing formation, time of existence and parameters of such structure are related to dynamics of the observation object (heart), to the use of individual combinations of perception codes, by the volunteers etc. It is supposed that localization of a single "cerebral area of attention" can not be universal for all individuals. An approach to the description of different types of attention to one's own heart is proposed in which attention is characterized based on distinguishing critical points or EEG registration zones in which the loss of system's stability is most likely reflected as transition to another functional state.
