缺水产生了寻找和消费水的动力。神经活动如何产生这种动机仍然知之甚少。我们使用活动依赖的遗传标记来表征下丘脑正中视前核(MnPO)中缺水激活的神经元。单细胞转录谱显示,脱水激活的MnPO神经元由一个单一的兴奋性细胞类型。在这些神经元的光遗传学激活后,小鼠喝水并执行操作性按压任务以获得水奖励,其速率与刺激频率成比例。这种刺激是令人厌恶的,而工具性暂停刺激可以加强按压。这些神经元的活动逐渐减少的过程中的操作会话。因此,脱水激活的MnPO神经元的活动建立了一个可扩展的,持久的和令人厌恶的内部状态,动态地控制口渴动机的行为。
Water deprivation produces a drive to seek and consume water. How neural activity creates this motivation remains poorly understood. We used activity-dependent genetic labeling to characterize neurons activated by water deprivation in the hypothalamic median preoptic nucleus (MnPO). Single-cell transcriptional profiling revealed that dehydration-activated MnPO neurons consist of a single excitatory cell type. After optogenetic activation of these neurons, mice drank water and performed an operant lever-pressing task for water reward with rates that scaled with stimulation frequency. This stimulation was aversive, and instrumentally pausing stimulation could reinforce lever-pressing. Activity of these neurons gradually decreased over the course of an operant session. Thus, the activity of dehydration-activated MnPO neurons establishes a scalable, persistent, and aversive internal state that dynamically controls thirst-motivated behavior.
