[Responses of neurons of a chronically isolated strip of cat auditory cortex to intracortical stimulation during paroxysmal electrical activity].
Responses of 155 neurons to single intracortical stimulation during paroxysmal electrical activity caused by series of frequent stimuli (10-20/c) by means of the electrical current were investigated extracellularly in the three-week isolated auditory cortex slab from non-anaesthetized tubocurarin immobilized cats. Depending on the behaviour of neurons during paroxysmal electrical activity and preservation of the ability to respond to intracortical stimulation all investigated neurons of the isolated slab were divided into four groups. Their distribution according to layers and duration of latent periods were investigated. It was shown that 2/3 of the investigated neurons generated impulse activity at the time of paroxysmal discharges, the rest did not manifest such activity.
