Abstract
Tetanus-induced long-term potentiation (LTP) of population action pote ntials at 22 degrees C was investigated in area CA1 of hippocampal sli ces prepared from hibernating (HH) and warm-acclimated Turkish hamster s (WH) and rats. LTP elicited at this temperature was significantly st ronger in HH slices compared to WH and rat slices. Hibernation-related improvement of the ability to develop longlasting enhancement of syna ptic transmission at low temperatures is interpreted as supporting hip pocampal function during arousal from hibernation.
