Dopaminergic receptors nyob qhov twg?
Dopamine receptors tau qhia nyob rau hauv lub hauv paus paj hlwb, tshwj xeeb hauv hippocampal dentate gyrus thiab subventricular zone. Dopamine receptors kuj qhia nyob rau hauv lub periphery, prominently nyob rau hauv lub raum thiab vasculature, Muaj tsib hom dopamine receptors, uas muaj xws li D1, D2, D3, D4, thiab D5.
