[Effect of electric stimulation of the parietal cortex on alimentary conditioned reflexes in dogs].
Changes in elaborated alimentary secretory reflexes were studied in dogs during bilateral electrical stimulation of the parietal cortex. It was found that a low-frequency (1 imp/s) continuous stimulation with subthreshold rectangular current exerts predominantly an inhibitory influence: on the beginning of stimulation, the spontaneous secretion and the secretion at intervals between the conditioned reflexes diminish, the latencies of conditioned reactions become longer, the conditioned secretion is reduced; at the same time unconditioned reflexes are retained and there is a tendency to their increase. High frequency (100 imp/s) stimulation with the same current is attended with an increase of conditioned, unconditioned and spontaneous secretion; however the latencies of conditioned reflexes are increased. Stimulation of the right hemisphere, contralateral to the side of secretion recording, exerts a more pronounced influence on the conditioned alimentary reflexes than that of the ipsilateral hemisphere.
