Abstract:
Unitary responses in the suprarhinal cortex were studied in anesthetized rats. Lateral amygdala stimulation gave rise to two types of cortical responses: (i) an excitatory response (59%) characterized either by a single spike discharge, or by a burst of two to four spikes, or (ii) an inhibitory response (41%) affecting cortical neurons which exhibited spontaneous discharge. The duration of inhibition appeared to be related to the intensity of stimulation and the spontaneous discharge frequency.
