^*Note: Cluster includes overlapping activation in the cerebellum and peristriate visual areas. Brain areas that showed significantly greater activation during error processing, response competition and inhibition and response execution. For each cluster, the activated region, number of voxels activated, maximum Z score and location of peak activation are shown.
