通过对舔体反应的计时研究了甜味和苦味对摄食的影响。给12只缺水大鼠15分钟的蔗糖（S）溶液（0.00%，1.25%，2.50%，含和不含奎宁（0.01%））和奎宁（Q）溶液（0.00%，0.0025%，0.005%和0.01%）含和不含蔗糖（5.00%）。摄食量和舔数随S增加而增加，随Q减少。在对S的反应中，爆发的次数增加，互舔间隔延长。在响应Q，舔摄入1毫升的解决方案，突发数，和缓慢舔的百分比增加，和突发大小减少。当Q和S混合在同一溶液中时，摄食反应的模式表现出两种味道的属性。结果表明2个独立的。同时运作的平行系统来控制老鼠的舔行为。一个系统表示S对摄入模式的影响，另一个系统表示Q的影响。
Effects of sweet and bitter tastes on ingestion were studied by timing licking responses. Twelve water-deprived rats were given 15-min access to sucrose (S) solutions (0.00%, 1.25%, 2.50%, and with and without quinine (0.01%) and to quinine (Q) solutions (0.00%, 0.0025%, 0.005%, and 0.01%) with and without sucrose (5.00%). Volume ingested and number of licks increased with S and decreased with Q. In response to S, the number of bursts increased, and interlick intervals lengthened. In response to Q, licks to ingest 1 ml of solution, burst number, and percentage of slow licks increased, and burst size decreased. When Q and S were mixed in the same solution, the pattern of ingestive responses manifested attributes of both tastes. Results suggest 2 separate. parallel systems that operate simultaneously to govern rats' licking behavior. One system expresses the effects of S on the pattern of ingestion and the other expresses the effects of Q.
