[Electroencephalographic analysis of a conditioned reflex to time].

EEG parameters in different cortical territories of free moving dogs were analyzed during formation of conditioned reflex to time, in situation of instrumental alimentary conditioning. It was shown that in organization of a reflex to time as a complex reaction(present, trace and rhythmic processes), different brain systems play different roles in the formation of its stages. Sensory systems provide for the complex of trace processes underlying reaction to time. Associative structures are involved in the afferent synthesis necessary for the present moment. Integrative-triggering formations attach formed reaction to a strictly fixed time.
