Wistar rats with cannulae bilaterally implanted in the CA1 region of the dorsal hippocampus were trained in a step-down inhibitory avoidance task. Through these cannulae they received an infusion of 28 or 280 ng per side of the L-type voltage-dependent calcium channel antagonist nifedipine, or of its vehicle (20% dimethyl sulfoxide in saline). The two doses(More)
The purpose of this research was to evaluate the role of hippocampal N-methyl-D-aspartate (NMDA) receptors in acquisition and consolidation of memory during shuttle avoidance conditioning in rats. Adult male Wistar rats were surgically implanted with cannulae aimed at the CA1 area of the dorsal hippocampus. After recovery from surgery, animals were trained(More)
The purpose of the present research was to further evaluate the role of hippocampal N-methyl-D-aspartate (NMDA) receptors in inhibitory avoidance task consolidation. Adult male Wistar rats were trained and tested in a step-down inhibitory avoidance task (0.4 mA footshock, 24 h training-test interval). Immediately after training, animals received a(More)
