title: [Comparison of the influence of the amygdaloid complex and the midbrain central gray substance on the neuronal activity of the lateral hypothalamus].
abstract: The influence of stimulation of stria terminalis and midbrain central gray substance on the neuronal activity of the lateral hypothalamus was studied in acute experiments on curarized rats. Five types of neuronal responses were found: 1) phase activation; 2) phase inhibition;3) diffusive activation; 4) diffusive inhibition; 5) two-phase responses. Stimulation of stria terminalis produced inhibition in 62.7% of the lateral hypothalamus neurons. 87% of those neurons were activated after stimulation of the central gray substance. The convergence of impulses from the amygdaloid complex and midbrain central gray substance was observed in 14.4% of reactive neurons. 84.6% of cells showed antagonistic convergent effects.
