In this issue of Neuron, Morrens et al. (2020) show that stimulus-evoked dopamine responses are enhanced by novelty and increase the rate at which animals acquire conditioned responses. These results provide a candidate neural mechanism for latent inhibition and illustrate a new role of dopamine signals in learning.
在本期《神经元》杂志上，Morrens 等人（2020 年）表明，刺激诱发的多巴胺反应会因新奇感而增强，并提高动物获得条件反应的速度。这些结果为潜伏抑制提供了一个候选神经机制，并说明了多巴胺信号在学习中的新作用。
