In this study, we investigate whether there are in vivo differences in GABA in the motor cortex and subcortical white matter of amyotrophic lateral sclerosis (ALS) patients compared with healthy controls. In 10 patients with ALS and 9 age- and sex-matched healthy controls, 3T edited proton magnetic resonance spectroscopy was performed to quantify GABA in primary motor cortex and subcortical white matter.
