Differential neuronal responses of performance during perceptual conflict.

<p>Regions of activation associated with the perceptual conflict condition between good and poor performers (p<.005 uncorr., k>70 voxels) and corresponding beta estimates. Using ANOVAs activation clusters elicited by good performers were seen in the RG (BA 11), ACC (BA 25), IPL (BA 40) and visual areas V2 and V3. Poor performers robustly activated only the IPL (BA 39). Corresponding beta estimates revealed significant differences between good and poor performers in any of these regions.
