The basal ganglia (BG) make up a prominent nexus between visual and motor-related brain regions. In contrast to the BG's well-established roles in movement control and value-based decision making, their contributions to the transformation of visual input into an action remain unclear, especially in the context of perceptual decisions based on uncertain visual evidence. This article reviews recent progress in our understanding of the BG's contributions to the formation, evaluation, and adjustment of such decisions. From theoretical and experimental perspectives, the review focuses on four key stations in the BG network, namely, the striatum, pallidum, subthalamic nucleus, and midbrain dopamine neurons, which can have different roles and together support the decision process.

基底神经节对视觉感知决策的贡献

基底神经节 (BG) 是视觉和运动相关大脑区域之间的重要联系。与 BG 在运动控制和基于价值的决策中的既定角色相反，它们对将视觉输入转化为行动的贡献仍不清楚，特别是在基于不确定视觉证据的感知决策的背景下。本文回顾了我们对 BG 对此类决策的形成、评估和调整的贡献的理解的最新进展。从理论和实验角度，综述重点关注 BG 网络中的四个关键站点，即纹状体、苍白球、底丘脑核和中脑多巴胺神经元，它们可以发挥不同的作用，共同支持决策过程。
