From Velanova et al., 2008. Voxels showing significant statistical activity change for correctly and incorrectly performed AS trials (i.e., correct and error trials) in adults, adolescents and children. (A) Horizontal sections show differing activity for correct and error trials, though similar distributions and levels of activity across age groups in supplementary motor area (SMA)/preSMA, frontal eye field (FEF), and posterior parietal cortex (PPC). (B) Horizontal sections show increased activity in putamen for correct trials relative to error trials in all age groups. Note that because maps are based on ANOVA, the direction of effects is not represented. Reprinted with permission from Cerebral Cortex.
