Post-trial reinforcing hypothalamic stimulation can facilitate avoidance learning.
Thirty seconds (0.2 sec on, 0.8 sec off) reinforcing electrical stimulation of the lateral hypothalamus of rats (presented 30 sec after the trial) facilitated learning of an avoidance task. This result was interpreted in terms of a direct influence of reinforcement on short-term memory processes.
