Hemispatial Neglect Shows That “Before” Is “Left”

Figure 1

Individual lesion mapping (in red) and group overlap for neglect patients (N+, left) and no-neglect patients (N−, right). Lesion reconstruction was performed on axial slices of a normalized magnetic resonance imaging brain template. In the group overlap colors code for the number of patients with damage to a given area (from 1 = violet to 6 (N−) or 8 (N+) = red). (A) Median split subtraction analysis, comparing the lesion in patients with spatial neglect versus without. Each color in the scale bar codes for a 16.67% frequency of lesion in one or the other group, except for the central purple color that represents −16.67 to +16.67%.
