Basal ganglia

Basal ganglia are a set of structures in the brain regulated by dopamine that play a role in action selection, voluntary movements and executive function, as well as perception of effort.

ME/CFS
A small study of chronic fatigue syndrome patients found increased choline in the basal ganglia. Increased choline can be a sign of immune activation or increased cell membrane turnover.
