Summary lesion information for non-improved versus significantly improved patients, in terms of the impact of prism exposure on left neglect in the chimeric/non-chimeric face discrimination task. Given the low number of patients in either subgroup (n = 3), this lesion information is presented here solely for exploratory descriptive purposes. A. Improved patients (n = 3). Overlap map showing the degree of involvement for each voxel in the lesions of the improved neglect group, normalized to the MNI template. The map is presented as axial renderings on the MNI ‘representative’ brain, in descending steps. 12 axial slices are shown that correspond to Z-coordinates 48, 36, 30, 24, 20, 16, 13, 3, −3, −6, −11 and −16 of the MNI space. The range of the colour scale derives from the absolute number of patient lesions. B. Overlap map for the non-improved neglect patients (n = 3). C. Non-improved minus improved patients. Contrast map showing the relative involvement (bins of 16.67%, apart from the purple shading which represents −16.67% through to +16.67%) of each voxel in the lesions of the non-improved patient group minus the improved patient group. The colour scale covers a range of voxel involvement in the two lesion groups, from involvement in the non-improved neglect group only (light blue) to involvement in the improved neglect group only (light red).
