Abstract
Three experiments investigated some effects of low-level stimulation on the amygdaloid complex (AMYG) and the mesencephalic reticular formation (MRF) in male Long-Evans rats. Exp I used a tilt box to test for motivational and/or reinforcement effects but failed to demonstrate these effects with stimulation of either structure. Exp II used a 1-trial fear-conditioning task and showed that stimulation of the AMYG disrupted retention when given immediately after training or, under some conditions, 4 days after training. Using the same task, Exp III showed that stimulation of the MRF enhanced retention when given immediately after training or, under some conditions, 4 days after training. Data indicate that under these conditions, modification of retention by low-level stimulation of specific brain structures is independent of the age of the memory.
