Without knowing what MTPT did (p. 520 in 2020FA) I reasoned through it like this:
Cholinergic in Nucleus Basalis of Meynert=ACh. Possibly but disease here causes alzheimers/huntingtons even though it is increased in parkinsons. Dopaminergic in neostriatum= Didn’t know so I just kinda ignored it 😂 Dopaminergic in substantia nigra = Parkinsons so it sounded like a good choice. Serotonergic in dorsal raphe nuclei = serotonin. A lack or excess here wouldn’t cause this. Serotonergic in locus ceruleus = norepinephrine. Same as last.
Ultimately chose dopaminergic in Sub. Nigra because of the rigidity on exam and feeling frozen in ice.
