Evoked responses recorded from the amygdala of the cat after sequentially pairing neocortical and hypothalamizic stimulation showed consistent suippression or depression of the response evoked by the test shocks, regardless of whether the cortical or subcortical site received the preceding conditioning shock. The possibility that functional interaction of neocortical and hypothalamic signals occurs in the amygdala is proved and an active inhibitory process is suggested.
