Conditioned insulin secretion and meal feeding in rats.

摘要: Previous researchers have reported that rats placed upon a feeding regimen such they receive only 2 hr of food per day (meal-fed rats) develop hyperinsulinemia at the time associated with feeding, even in absence food. Controls fed ad lib had no response. In series several experiments, meal-fed elevated insulin levels specific and increment could be eliminated atropine. Free-feeding controls, on other hand, always higher than rats, did not an elevation normally ate, values were unaffected by Further experimentation showed become arbitrary stimuli eating for rats. It is concluded their learned
