摘要

在最近的一项研究中，Goueytes及其同事将计算模型与颅内记录结合起来，剖析了信心和思维变化的神经基础。它们揭示了一种有时间组织、空间分布的证据积累层次结构，其中决策前信号位于前辅助运动区（preSMA），决策后信号位于脑岛。这将元认知重新定义为一个分布式和动态的过程。

Pre- and post-decision signals of certainty in changing minds.

In a recent study, Goueytes and colleagues combined computational modeling with intracranial recordings to dissect the neural basis of confidence and changes of mind. They reveal a temporally organized, spatially distributed hierarchy of evidence accumulation, with pre-decisional signals in the pre-supplementary motor area (preSMA) and post-decisional signals in the insula. This reframes metacognition as a distributed and dynamic process.
