Overlap of the 50% isocontour of the cytoarchitectonic areas with the lesion (white contour line) in common reference space for Patient 1. Horizontal and sagittal sections through the hand area as defined by the average z‐ and x‐coordinates of Boecker et al. [1995]. The lesion overlaps with areas BA 3a and 3b of the anterior bank of the postcentral gyrus and BA 4a and 4p of the motor cortex. Color coding: dark green = BA 4a, light green = BA 4p, red = BA 3a, orange = BA 3b, yellow = BA 1, blue = BA 2, purple = area IP1, magenta = area IP2.
