The effects of immediate post-training infusions of various doses of UK 14,304 (a selective α₂-adrenoceptor agonist) into the basolateral amygdala on inhibitory avoidance retention latencies. Error bars represent mean ± SEM latency (in seconds) to enter the dark compartment on the retention test. Pre-training groups were infused 20 min before training whereas post-training groups were infused immediately after the footshock administration. **P < 0.01 compared with the corresponding group of the other condition; ***P < 0.001 compared with vehicle-injected group; •••P < 0.001 compared with 0.1 and 1.0 ng of UK 14,304-injected group; ◆◆P < 0.01 compared with 1.0 and 3.0 ng of UK 14,304-injected group. n = 9–12 per group.
