oles of orexin neuron on the reward based spontaneous voluntary behavior

为了了解纹状体在基于价值和策略的决策中的作用以及下丘脑的食欲素神经元在基于奖励的自发行为中的作用，我们记录了猕猴和大鼠的纹状体和食欲素神经元，它们编码了个体决策和行动的积极和消极结果反馈。在下丘脑区进行细胞旁记录，用免疫组织化学方法观察增食欲素神经元。这个样本目前正在分析中。这些活动特征作为决策变量的异质表示，可能是对纹状体中选定动作进行强化和基于策略的评估过程的一部分。

To understand the role of the striatum in value- and strategy-based decision-making and hypothalamic orexin neuron in reward based spontaneous ehavior, we recorded striatal and the orexin neurons in macaque monkeys and rats Large subsets of striatal neurons encoded positive and negative outcome feedbacks of individual decisions and actions. Juxtacellular recording was made in hypothalamic area and investigate orexin neuron by means of immunohistochemical method. This sample is presently being analyzed. These activity profiles as a heterogeneous representation of decision variables may underlie a part of the process for reinforcement- and strategy-based evaluation of selected actions in the striatum.
