ABSTRACT
Dopamine(DA) modulates diverse wake-related behaviors including movement,reward, and cognition.Dopaminergic neurons are located in the substantia nigra pars compacta and ventral tegmental area.There are five distinct DA receptors(R)D_1R,D_2R(D_(2S)R and D_(2L)R), D_3R,D_4R and D_5R in the central nervous system, in which D_1R and D_2R are majorly expressed. The affinity of D_2R for endogenous DA is significantly higher than that of D_1R.Re- cently,studies by pharmacological and gene knock-out animals revealed that dopamine D_2R is essential inmaintaining wakefulness.Here,we review the progress on roles of D_2R in sleep-wake regulation.
