Title: [Evoked impulse activity in a neuronally isolated cortex].
Abstract: The reactions of neurons of the isolated cortex of one hemisphere to direct cortical stimulation were investigated in cats under Nembutal anesthesia. Isolation of the cortex was carried out by Khananashvili's method [10]. It is shown that phasic reactions develop in the isolated cortex in response to such stimulation: initial discharge, initial pause, first after-discharge, first after-pause, late after-discharges and pauses, as well as reactions of presumably inhibitory neurons. A majority of the cells (85%) which manifest background activity respond to direct electrical stimulation, and the frequency of the late after-reactions is twice as great as in the intact cortex. It is concluded that cortical elements of the isolated cortex retain their principal neurophysiological properties.
