The Striatal neurons are currently labeled as “Putamen” which would lead to confusion if a test stem referenced the “striatal neurons” that are the sites of Huntington’s lesions. I think it is appropriate in this section to repeat that Dopamine is inhibitory through its D2 receptor (currently unmentioned) and stimulatory through its D1 receptor.
