改变想法？并非如此——尾状核的活动和连通性与选择的变化相关。

Changes in preference are inherently subjective and internal psychological events. We have identified brain events that presage ultimate (rather than intervening) choices, and signal the finality of a choice. At the first exposure to a pair of faces, caudate activity reflected the face of final choice, even if an initial choice was different. Furthermore, the orbitofrontal cortex and hippocampus exhibited correlations only when the subject had made a choice that would not change.
偏好的变化本质上是主观的内部心理事件。我们已经识别出预示最终（而非中间）选择并表明选择已确定的大脑活动。在首次接触一对面孔时，尾状核的活动反映了最终选择的面孔，即使最初的选择不同。此外，只有当受试者做出不会改变的选择时，眶额皮质和海马体才会表现出相关性。
