FEF-L, FEF-R, PPC-L, PPC-R, and CV used both anatomical markers and functional activity to define the mask. Broca-L and Broca-R used only anatomical markers to serve as a control ROI to study the variability within a nonstimulated ROI.

Broca, Broca's region; CI, convergence insufficiency; CV, cerebellar vermis; FEF, frontal eye field; HC, healthy control; L, left; R, right; PPC, posterior parietal cortex; ROIs, regions of interests.
