[EEG-correlates of direct and reverse conditioned connections in a food-getting reflex formed to electric stimulation of the lateral geniculate body].

In the course of formation of a food-procuring conditioned reflex to low-frequency electrical stimulation of the cat LGB, the corresponding evoked potentials underwent a change: the main negative component of the evoked potential in the visual area of the cerebral cortex increased; a distinct evoked potential not recorded before conditioning appeared in the sensorimotor area. The changes are regarded as EEG-correlates of formation of a forward conditioned connection. In tests with an isolated presentation of the reinforcing stimulus, a 6--8 c/s rhythm was recorded in the visual cortical area, similar to that of conditioned stimulation of LGB and considered as an EEG-correlate of a backward conditioned connection.
