In this issue of Neuron, Nguyen and colleagues (Nguyen et al., 2021) investigate nicotine’s effects on diverse midbrain dopamine neurons. Their findings provide new understanding of the functional role of ventral tegmental area (VTA) dopamine neurons and reveal topographically distinct, pathway-specific, and opposite dopaminergic responses to nicotine that likely mediate reward and anxiety, respectively.

尼古丁复杂性和多巴胺异质性的持续传奇:尼古丁激活和抑制调节奖赏和焦虑

在本期Neuron中,Nguyen 及其同事(Nguyen 等人,2021 年)研究了尼古丁对不同中脑多巴胺神经元的影响。他们的发现提供了对腹侧被盖区 (VTA) 多巴胺神经元的功能作用的新理解,并揭示了可能分别介导奖赏和焦虑的对尼古丁的地形独特、通路特异性和相反的多巴胺能反应。
