[The regulatory effect of the functional status of the cat on the perception of an external afferent stimulus].
Experiments were conducted on cats by conditioned food-procuring method. Behavioural, vegetative reactions and a set of electrophysiological characteristics were recorded. It was found that regulatory influence of an extraneous stimulus and of artificial excitation of the brain was expressed in an increase of reactivity to conditioned and unconditioned sensory stimuli and in disinhibition of effector responses. This influence was realized not only during the development of EEG activation reaction but could be preserved over a long period in conditions of the deactivated brain state. Regulatory influence of interceptive factors is characterized by a decrease of reactivity and by inhibition of effector responses. As in the case of external effects, the realization of this influence begins with a period of brain activation and is preserved for a long time in conditions of deactivated state.
