Abstract

Eating, drinking, irritability, muricide, and copulation were measured in 45 male rats before and after one of three coronal knife cuts in the septal region or a control operation; in addition, activity was measured postoperatively. (a) Cuts posteroventral to the septum resulted in slight hypophagia, marked hyperdipsia, irritability, asexuality, and decrease in activity. (b) Cuts of the fornix resulted only in slight decrease in activity. (c) Cuts through the anterior septum resulted in irritability, slight hyposexuality, and slight decrease in activity. No significant correlations between the various behavioral effects were found. It was suggested that the neural pathways mediating eating, drinking, irritability, muricide, copulation, and activity are relatively distinct and that neural activity in the septal region probably does not influence behavior in any unitary fashion.

摘要

在45只雄性大鼠的中隔区域进行三种冠状切口之一或对照手术后，对其进食、饮水、易怒性、杀鼠行为和交配情况进行了术前和术后测量；此外，还对术后的活动情况进行了测量。(a) 中隔后腹侧切口导致轻微的摄食减少、明显的饮水过多、易怒、无性行为以及活动减少。(b) 穹窿切口仅导致活动略有减少。(c) 穿过前中隔的切口导致易怒、轻微的性能力减退以及活动略有减少。未发现各种行为效应之间存在显著相关性。研究表明，介导进食、饮水、易怒性、杀鼠行为、交配和活动的神经通路相对独立，中隔区域的神经活动可能不会以任何单一方式影响行为。
