Abstract
Naive rats raise a panel in approaching food more often after their first insulin injection than after a control injection. At the same time there is a reduced incidence of long pauses in feeding under the influence of injected insulin. Also, the size of the first feeding bout after injection and its ratio to the delay before the next feeding bout both increase. This suggests that insulin elicits hunger by attenuating satiety signals.
