用15只雄性Wistar大鼠研究了味觉对定量控制摄食和体重的作用。联合切断双侧鼓索、舌咽神经和迷走神经咽分支可产生味觉传入阻滞。该程序没有影响口腔的状况，损害对感官刺激的定向，或严重破坏消费序列。然而，deafferented的SS表现出降低对食物和水的反应，盐酸奎宁厌恶阈值升高，摄食效率受损。术后至少40-50天，食物和水摄入量以及体重保持低于对照水平。食物摄入量不足时，没有观察到Ss提供即兴pablum，结果表明，增加适口性可以弥补减少味觉输入。通过不同的饮食类型恢复食物摄入的顺序表明对味觉刺激的反应性提高。味觉传入阻滞的效果进行了比较后，部分三叉神经orosensory神经，和口腔味觉和口腔触觉的差异贡献进行了讨论。(42参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Studied the contribution of taste to the quantitative control of intake and body weight in 15 male Wistar rats. Gustatory deafferentation was produced by combined bilateral section of the chorda tympani and glossopharyngeal nerves and the pharyngeal branch of the vagus nerve. The procedure did not affect the condition of the mouth, impair orientation to sensory stimuli, or severely disrupt the consummatory sequence. Nevertheless, deafferented Ss showed reduced responsiveness to food and water, elevated quinine HCl aversion thresholds, and impaired feeding efficiency. Food and water intake and body weight remained below control levels for at least 40–50 days postoperatively. Food intake deficits were not observed when Ss were offered ad lib pablum, a result suggesting that increased palatability could compensate for decreased gustatory input. The order of recovery of food intake through different diet types suggests a heightened responsiveness to taste stimuli. The effects of gustatory deafferentation are compared with those seen after section of trigeminal orosensory nerves, and the differential contributions of oral taste and oral touch are discussed.(42 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
