Nio and colleagues address an important question about how the cerebellum and ventral tegmental area (VTA) contribute to the extinction learning of conditioned fear associations. This work tackles a ...

多巴胺在攻击行为中的作用充满了矛盾。传统观念认为，多巴胺的释放会激发个体的行动能力，但现实却更为复杂。例如，某些增加多巴胺水平的药物（如苯丙胺和甲基苯丙胺）在高剂量下可能引发更具侵略性的行为。然而，这种效应并非恒定，还受到剂量、行为背景以及个体经验等 ...

大脑的奖赏系统与动机、情感和成瘾行为密切相关。传统研究认为，奖赏效应主要由大脑的腹侧被盖区（VTA）和伏隔核（NAc）等区域调控。然而，近年来的研究逐渐揭示，其他脑区也可能在奖赏机制中发挥重要作用。

Like humans, mice will compete over territory and mates, and show increased confidence in their fighting skills the more they win. At first, a brain chemical called dopamine is essential for young ...

In experiments in rodents, a team led by researchers at NYU Langone Health boosted activity in dopamine-releasing cells in a part of the brain called the ventral tegmental area. The findings revealed ...

New research suggests that mood swings in bipolar disorder are regulated by two clocks: the body’s 24-hour circadian rhythm ...

Synaptic plasticity is the biological process by which specific patterns of synaptic activity result in changes in synaptic strength and is thought to contribute to learning and memory. Both pre ...

Utilizing dual-color fiber photometry calcium recordings alongside projection-specific chemogenetic and optogenetic manipulations of dopaminergic neurons in the ventral tegmental area (VTA), the ...
