[Patterns in the development of habituation in the cortical area of the visceral analyzer].

In anesthetized cats, a gradual decrement of direct cortical responses was studied in associative and SII cortical areas, in neuronally isolated and in intact cortex. The habituation of direct cortical responses was more rapid in associative area of the intact cortex after deafferentiation of the cerebral hemisphere than in the neuronally isolated cortex. The mechanism of habituation in intact cortex of animals with neuronally isolated cortex is discussed.
