神经调节剂血清素 (5-HT) 与涉及耐心或冲动控制的多种功能有关。其中许多效应与长期存在的理论一致,即 5-HT 会促进行为抑制,这是一种有利于被动行为而不是主动行为的动机偏见。为了进一步检验这个想法,我们研究了 5-HT 在概率觅食任务中的影响,在该任务中,小鼠必须学习环境统计数据并推断何时离开耗尽的觅食地点进行下一个觅食。至关重要的是,小鼠需要主动戳鼻子才能利用给定的位置。我们表明,中缝背核中 5-HT 神经元的光遗传学激活增加了小鼠在放弃之前积极尝试利用奖励位点的意愿。这些结果表明行为抑制并不能充分描述 5-HT 功能,并表明统一的解释必须基于高阶函数。血清素(5-HT)被认为可以通过行为抑制来促进等待。在这里,作者使用主动觅食任务和 5-HT 神经元的光遗传学激活来表明,这些神经元不是被动的,而是在面对延迟时增强了持久性。
The neuromodulator serotonin (5-HT) has been implicated in a variety of functions that involve patience or impulse control. Many of these effects are consistent with a long-standing theory that 5-HT promotes behavioral inhibition, a motivational bias favoring passive over active behaviors. To further test this idea, we studied the impact of 5-HT in a probabilistic foraging task, in which mice must learn the statistics of the environment and infer when to leave a depleted foraging site for the next. Critically, mice were required to actively nose-poke in order to exploit a given site. We show that optogenetic activation of 5-HT neurons in the dorsal raphe nucleus increases the willingness of mice to actively attempt to exploit a reward site before giving up. These results indicate that behavioral inhibition is not an adequate description of 5-HT function and suggest that a unified account must be based on a higher-order function. Serotonin (5-HT) has been suggested to promote waiting through behavioral inhibition. Here, the authors use an active foraging task and optogenetic activation of 5-HT neurons to show that rather than passivity, these neurons enhance persistence in the face of delay.
