腹侧纹状体(VS)中的神经元对预测不同价值奖励的线索进行激发。目前尚不清楚这种活动是否代表与预期奖励相关的价值或奖励预期引起的动机水平。为了区分这两者,我们训练大鼠完成一项任务,在这项任务中,我们通过操纵正确试验预期的奖励大小和错误时预期的惩罚威胁来独立改变价值。我们发现,VS中不同的神经元群体编码期望值和动机。
Neurons in the ventral striatum (VS) fire to cues that predict differently valued rewards. It is unclear whether this activity represents the value associated with the expected reward or the level of motivation induced by reward anticipation. To distinguish between the two, we trained rats on a task in which we varied value independently from motivation by manipulating the size of the reward expected on correct trials and the threat of punishment expected upon errors. We found that separate populations of neurons in VS encode expected value and motivation.
