Rats received low-level bilateral electrical stimulation of the amygdala after training on a one-trial inhibitory (passive) avoidance task. The stimulation did not produce brain seizures. Animals which received the stimulation 5 sec or 1 hr, but not 6 hr, after training had retrograde amnesia as measured on a retention test 24 hr later. The amnesia was permanent over an 8 day period. Following extinction and retraining, amygdala stimulation produced retrograde amnesia only in animals which had complete amnesia (i.e., animals which performed at the naive level) for the first training experience.
