[Neuronal activity of the midbrain central grey upon stimulation of the amygdaloid complex and the subthalamus].

The influence of stimulation of the amygdaloid complex and the subthalamus on neuronal activity of the central grey substance were studied in acute experiments on rats. The amygdaloid stimulation produced inhibition in 72% of the central grey substance neurons; stimulation of subthalamus--activation in 59%. Repetitive stimulation of the amygdaloid complex evoked prolonged changes in the neuronal activity. The convergence of impulses from the amygdaloid complex and subthalamus was observed in 31 of 114 reactive neurons. 71% of cells showed inhibition.
