[Change in integrative states of cortical neurons at consecutive stages of systemic behavior pattern]

Cats were trained to press the level after sound conditional stimulus. The spike activity of visual and parietal cortex neurons was registered during this operant feeding behavior, bring activity patterns were individual and their reorganization was observed during interstimulus non-reinforced pressings of the lever and this corresponded to prolongation of a manipulation-reinforcement interval. Thus, the firing pattern reflects the functional state of the neuron and its synaptic activation; the changes in spike activity reflect the alterations in the neuronal integrative state.
