Rats were offered a forced choice between a train of brain stimulation that varied in strength from trial to trial and a fixed standard reward. This standard reward consisted of an intraoral sucrose infusion presented either alone or paired with an equipreferred train of brain stimulation. Postingestional effects were minimized by opening a gastric cannula. The presence of a sucrose standard led the subjects to forgo trains of brain stimulation for which they had responded when the sucrose was… CONTINUE READING
