a(MESH:"Pars Compacta") association p(HGNC:CHRM5)
M5 mAChR is predominantly distributed in the pars compacta of the substantia nigra, a structure that provides dopaminergic innervation to the striatum, and in the ventral tegmental area, a structure providing dopaminergic innervation to the nucleus accumbens and other limbic areas[26, 57]. These areas are well known to play a critical role in the rewarding effects of several drugs of abuse. M5 mAChR-knockout mice are less sensitive to addictive drugs such as morphine and cocaine[58].
