In previous studies we showed that electrical stimulation of the lateral hypothalamus of 15 day old rats significantly enhanced the learning of various tasks examined 4 weeks later. We first demonstrated that this stimulation improved the acquisition and extinction of a food-reinforced task (Velley and Cardo, 1977). In subsequent experiments, we observed the same effect on the acquisition and reversal of a light-dark discrimination whether appetitively or aversively reinforced as well as on the acquisition of a one way avoidance task (Velley et al., 1981b).
