Magnetic resonance spectroscopic images for patients with SCI and spasticity, patients with SCI but no spasticity, and healthy controls.

(A–F) Sagittal, axial, and coronal T1-weighted images showing the location of the 10-mm³ voxel (at the crosshairs) in the left precentral gyrus (PG) (A) and left basal ganglia (BG) (B) of a patient with SCI and spasticity, the left PG (C) and left BG (D) of a patient with SCI but no spasticity, and the left PG (E) and left BG (F) of a healthy participant. The region of interest in the PG was adjacent to central sulcus, and that in the BG was adjacent to internal capsule. The exact location was determined by a single experienced radiologist who was completely unaware of the experimental grouping. SCI: Spinal cord injury.
