  • Title: [Effect of electric stimulation of the amygdala on orbital cortex neurons during learning and performance of a conditioned alimentary reflex].
    Author: Shuvaev VT.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1981; 31(6):1149-56. PubMed ID: 7331502.
    Abstract:
    The influence of stimulation of the amygdala nuclei complex on the orbital cortex neurones during the formation and realization of the alimentary conditioned reflex was studied in chronic experiments on three dogs. In the course of alimentary conditioning, a qualitative change of the histograms of distribution of interimpulse intervals (III) took place. Other parameters of spike activity, also underwent changes: the mean frequency of discharges and the degree of regularity of the spike flow. Single stimulation of the amygdala decreased the mean frequency of discharges of the orbital cortex neurones, diminished the secretory conditioned reflex, reduced the regularity of the spike flow and qualitatively changed the III distribution histogram. An attempt has been made to explain the mechanism of action of the amygdala nuclei stimulation on the conditioned reaction.
