在大鼠中，由口腔食物引起的口腔刺激产生了一种刻板的消化反应序列，并在营养物质被吸收到血液之前迅速释放胰岛素。当有害的味觉刺激被注入口腔时，一组不同的，令人厌恶的完成反应被唤起，并且不释放胰岛素。将有苦味的味觉溶液与LiCl配对，足以逆转该味觉从摄入到厌恶的随后呈现的圆满反应序列，并消除胰岛素对该味觉的预吸收释放。这表明了一种由经验产生的味觉适口性的转变。一种可口但绝对不含热量的味道会引起行为摄入，但不会释放胰岛素。独立但相关的控制系统运作产生圆满行为和摄取性神经内分泌反应。
The oral stimulation arising from food in the mouth produces a stereotyped sequence of ingestive consummatory responses in rats and a rapid release of insulin prior to the absorption of nutrients into the blood. When noxious taste stimuli are infused into the mouth, a different, aversive set of consummatory responses is evoked and no insulin is released. Pairing a sapid taste solution with LiCl suffices to reverse the consummatory response sequence to subsequent presentations of that taste from ingestion to aversion and to abolish the preabsorptive release of insulin to that taste. This indicates an experience-produced shift in the palatability of the taste. A palatable but categorically noncaloric taste elicits behavioral ingestion but no insulin release. Separate but related control systems operate to produce consummatory behavior and ingestive neuroendocrine responses.
