Representative images showing distributed regions of interest. Multiple circular areas, 10 mm in diameter, were placed on the magnetic resonance imaging (MRI) averaged from 10 images from each subject's co-registered positron emission tomography –MRI image, which was resliced at a thickness of 5 mm. The Montreal Neurological Institute coordinate in the z dimension is given for each slice. R indicates right side of the brain. M1Leg, primary motor cortex for legs; SMA, supplementary motor cortex; S1Leg, primary sensory cortex for legs.
