[The inhibitory effect of the presentation of extraneous stimuli on the neuronal impulse reactions of the cat parietal cortex in a conditioned reflex].
Spike activity of neurons (area 7) was studied during conditioned placing reflex in the rest, during appearance and extinction of the orienting reaction in trained cats. Spike activity was studied also during unconditioned electro-cutaneous stimulation of the contralateral forelimb in untrained cats. Conditioned movements and electrocutaneous stimulation occurred without specific spike reactions of neurons due to the effect of the external stimulation on attention of animals. It is suggested that appearance of spike responses of neurons to the stimulation only reflects the processes in structures that take part in the triggering and realization of the reflex.
