[The spectral characteristics of the rabbit neocortical biopotentials during the termination of a dominant for thirst].

[Article in Russian]


Spectral analysis of neocortical electrical activity of rabbits during learning blinking reaction which was directed to cessation of thirst dominant, revealed significant increase of the spectral power most pronounced and regular in the delta-range. On the basis of these data a conclusion is drawn that during the goal-directed behaviour of the animal the cortical structures are involved in the dominant constellation. Comparison of the spectral characteristics of potentials recorded in three successive 5-second intervals which preceded blinking, revealed a certain specificity (temporal and related to different frequency ranges) of changes in electrical activity in different cortex areas. These findings reflected functional ambiguity and phase course of the processes which accompany preparation for the goal-directed reaction.
