Intrahemispheric Perfusion in Chronic Stroke-Induced Aphasia

Figure 1

Lesion overlap map for 35 participants with aphasia, by axial slices (a) and with a three-dimensional view (b), using the neurological convention (left hemisphere is on the left). The color bar indicates the degree of overlap from minimal overlap (violet; participants overlapping) to maximum overlap (red; participants overlapping). The overlap map was spatially smoothed (3 mm).
