title: [Changes in evoked potentials during differentiation inhibition].
abstract: Evoked responses (EPs) of the auditory and the sensorimotor cortical areas were studied in experiments on cats during formation of a positive food-procuring conditioned reflex to a rhythmic sequence of clicks and during formation of the differentiation inhibition in response to the clicks of the same parameters, but with different frequency. In the positive conditioned reflex the EPs amplitude in the sensorimotor cortex increases; they are enriched by late components and in their general configuration they become much similar to EPs in the auditory area. The EPs patterns both in the auditory and in the sensorimotor areas considerably change in response to the differentiation stimulus, but differently in each of the sites.
