Figure 1. Supplemental motor area- primary motor cortex pathways with altered white matter microstructure.

Figure 1

Mean maps averaged on both groups and overlaid on mean-FA images are displayed for the left pre-SMA-SMA-proper (first row) und the right SMA-proper-M1 (second row) connection. The voxel values represent an estimation of the probability that the voxel is part of the fibre bundle of interest (PIBI). To remove random artefacts, only voxels with PIBI values >0.0148 were included in probability maps [52], [53]. Maximum PIBI values are displayed at the top of each colour bar. The displayed figures illustrate anatomical pathways from where mean-MD values have been extracted.
