Abstract
In order to investigate the behavioral role of pontine gigantocellular field (FTG) units, we have operantly reinforced discharge in these cells in unrestrained cats using lateral hypothalamic stimulation as the reinforcing stimulus. Cats readily learned to increase discharge rate in reinforced FTG cells relative to simultaneously recorded, non-reinforced control cells. Increased FTG discharge was associated with elevated levels of motor activity and often with stereotyped movements. Our results are compatible with the hypothesis that FTG unit discharge is related to specific movements.
摘要
为了研究脑桥巨细胞区（FTG）神经元的行为作用，我们在未受约束的猫身上，通过使用下丘脑外侧刺激作为强化刺激，对这些细胞的放电进行操作性强化。相对于同时记录的未强化对照细胞，猫很容易学会提高强化的FTG细胞的放电率。FTG放电增加与运动活动水平升高相关，且常伴有刻板运动。我们的结果与FTG神经元放电与特定运动有关的假设相符。
