Brain regions associated with hypoesthesia, excluding spatial neglect. Results of the VLSM 2.55 t-statistics excluding patients with right-sided brain lesions and spatial neglect (shown in turquoise). Shown are the same axial brain slices as in Fig. 1. The results of the analysis without neglect patients are superimposed on the statistical map of the whole sample (shown in yellow-orange, same as in Fig. 1). The t-statistics without neglect patients, revealed a smaller topographic extend of hypoesthesia-associated lesions as for the whole group, but nevertheless the same set of brain regions (i.e., primary somatosensory areas BA 1, 2, 3a and 3b, BA 4p on the primary motor cortex, the IPL and IPS, ventral premotor cortex BA 6 plus BA 44, S2-associated parietal opercular subdivisions OP 1 to 4, insular cortex). Numbers above each brain slice indicates corresponding z coordinate in MNI space. The white line in brain slices from z = 27 to z = 52 indexes the central sulcus. Colour bars indicates T-scores across lesion maps (blue to green for lesion maps excluding neglect, red to yellow for the whole sample). White lines crossing the little brain in the last row index the position of the presented brain slices.
