Summary table neuroimaging studies directly comparing RI in visual and verbal domains.

STUDIES	NEURAL REGIONS		TASKS
	VERBAL	VISUAL
Stephan et al. (2003)	left anterior cingular cortex, left IFG, fusiform gyrus, lateral extrastriate cortex, ventral premotor cortex and posterior IFG, supplementary motor cortex, bilateral primary visual cortex	anterior and posterior right inferior parietal lobule	Letter and visuospatial decision tasks
Morimoto et al. (2008)	left frontal inferior cortex	right frontal inferior cortex	Flanker tasks
Schumacher et al. (2011)	left inferior frontal gyrus	cingulate gyrus, left precentral gyrus, SMA, inferior temporal gyri, left post central gyrus, fusiform gyri, left superior and inferior parietal lobule, left and right middle and inferior occipital gyrus, left superior occipital gyrus, cerebellum, left putamen and thalamus	Flanker tasks
	both: bilateral precentral gyri and left superior frontal gyrus, supramarginal gyrus, supplementary motor area, and putamen

Notes: IFG = Inferior frontal gyrus, SMA = supplementary motor area.
