  • Title: [Effect of switching off the globus pallidus on alimentary and electrophysiologic responses induced by stimulation of the hypothalamus].
    Author: Lukhanina EP, Litvinova AN.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1977; 27(3):505-12. PubMed ID: 899253.
    Abstract:
    In chronic experiments on eight cats a direct electrical stimulation of the lateral hypothalamus evoked: 1) food eating in a state of satiation and 2) a reproduction of a conditioned food-procuring reflex, preliminarily elaborated to an acoustic signal. Bilateral electrolytic ablation of the globus pallidum abolished both reactions, but for different time periods. The first one was restored spontaneously on the 20th to the 46th day; the second disappeared for 2.5 to 8.5 months without spontaneous restoration. Stimulation of the lateral hypothalamus alimentary zones brought about a statistically significant rise of the thresholds of desynchronization reactions in the ipsi- and contralateral sensorimotor cortex. The activating role of the globus pallidum in the organization of a motivational alimentary excitation is discussed.
