Changing the mind? Not really-activity and connectivity in the caudate correlates with changes of choice

Soc Cogn Affect Neurosci. 2014 Oct;9(10):1546-51. doi: 10.1093/scan/nst147. Epub 2013 Sep 13.

Abstract

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.

Keywords: caudate; changing mind; fMRI; face preference; gaze manipulation.
