Conclusions 1. Differences have been found in the functional properties close-lying neurons of area 18 of the visual cortex of wakeful cats recorded in pairs by a single electrode, in the initial state prior to learning, and in the dynamics of the learning of visual differentiation of bars of light of various orientations. 2. Prior to learning, neurons generating low-amplitude spikes exhibit primarily reactions of the phasic type, while in neurons generating high-amplitude spikes, variable reactions were observed, but more often, reactions of the tonic type. 3. Plastic restructurings in the dynamics of the learning of visual recognition appeared in the first place in neurons generating low-amplitude spikes. These restructurings were characterized by change in the frequency of impulse activity. Neurons generating high-amplitude spikes were involved later in the process of learning; their restructurings of impulse activity consisted in change in the character of the responses to the stimuli employed. 4. The frequency of discharges of close-lying neurons of the visual cortex increased, as did the correlatability of their discharges as compared with the initial state. 5. It was found that a monotypal pattern of the reactions of close-lying neurons of the visual cortex was generated during learning, independent of the orientation of the visual stimuli, which attests to the possibility of dynamically regulable change in the state of the cortical neurons.
