  • Title: [Discriminative and extinctive inhibition of alimentary conditioned reflexes against a background of electric stimulation of the parietal cortex].
    Author: Danilova LK.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1981; 31(5):933-40. PubMed ID: 7314913.
    Abstract:
    Changes in differentiation and extinction inhibition of alimentary secretory conditioned reflexes during electrical stimulation of parietal cortical zones with a weak subthreshold current of 1 to 100 imp/s frequency were studied in dogs with electrodes implanted in the cerebral cortex. It was found that stimulation of these associative cortical areas results in disinhibition of differentiation inhibition. The depth of the disturbance depends on the frequency of the stimulating current: with high frequency stimulation, the effects of disinhibition are much more pronounced. Extinction of the conditioned alimentary reflex to an acoustic stimulus during stimulation is also impeded and is accompanied by motor alimentary excitation, particularly when the parietal cortex is stimulated by the high-frequency current.
