自动行为被打断时眶额皮层价值动态与纹状体群体几何
Orbitofrontal value dynamics and striatal population geometry during interruption of automatic behavior
AI 导读
Elston 与 Wallis 考察猴子如何用认知控制覆盖自动行为：认知冲突使眶额皮层（OFC）价值表征变得不稳定，并增强其与纹状体的振荡同步，同时伴随纹状体编码失稳和自动反应中止。据此提出，控制并非“抑制”纹状体，而是以“干扰”方式运作。
摘要
Elston and Wallis examined how monkeys use cognitive control to override automatic behavior. Cognitive conflict made OFC value representations volatile and increased oscillatory synchronization with the striatum, which coincided with destabilized striatal coding and halting of the automatic response. This suggests that control operates by “jamming” rather than “suppressing” the striatum.
