[Changes in neuronal responses of area 7 of the cat cerebral cortex to unconditional and conditional stimulation with additional stimuli].
Influence of external stimuli and food motivation on neuronal spike responses (area 7) induced by conditional and unconditional stimulation were studied in the awake cats. The beginning of external stimuli and food motivation inhibited neuronal responses after electro-cutaneous stimulation. During external stimulation after the reflex onset conditional neuronal reactions were later by 50-250 ms, but the latencies of conditional movements did not change. Identical changes of neuronal responses were during variation of food motivation. It is supposed that the reason of the studied phenomenon is variation of the exteroceptive attention level of cats induced by changes in experiment conditions.
