Figure 3. Spatial extent of selected features inside M1 and S1.

Figure 3

A: Mapping of features (250 most activated voxels) for one representative subject (subject A5), for M1 and S1 on left and right hemisphere grids. The dashed line indicates the central sulcus. Around the central sulcus, M1 and S1 ROIs may overlap due to the transformation into tile space and partial volume effects. Triangles indicate the center of mass of M1 and S1, and the number represents the ROI’s ‘spatial extent’, measured in mesh tiles. B: ROIs of all subjects. The color per tile indicates the number of subjects having that tile selected as a feature for classification. C:centers of mass for all subjects for both M1 and S1 on the left and right hemispheres. D: Spatial extent of features per hemisphere in M1 and S1 for controls and amputees (mean with 95% confidence interval). There was no significant difference in spatial extent between left and right hemispheres, or between controls and amputees.
