Decreased fractional anisotropy (FA), decreased N-acetylaspartate (NAA), increased myo-inositol (mI), and decreased γ-aminobutyric acid (GABA) levels in amyotrophic lateral sclerosis (ALS) patients. Circles represent respective values of FA in the corticospinal tract (A), NAA in the left motor cortex (B), mI in the left motor cortex (C), and GABA levels in the left motor cortex (D) for individual ALS patients and healthy controls (HC). Horizontal bars indicate the mean. IU, institutional units.
