Mean (±S.E.M.) number of ultrasonic vocalization (USV) responses of Postnatal Day 12 rat pups abruptly isolated in a novel cage for a 3min observation period. During three 30sec epochs, D5W was infused into the pups’ jugular cannulas. Rates of infusion were 6, 9, and 12μl/30sec. The 3 control epochs without infusion were temporally matched to the experimental epochs [92]. Reprinted by permission of Behavioral Neuroscience.
