abstract：:CIRCLING training (CT) decreases muscarinic acetyl-choline receptor (mAchR) binding in rat striatum. As cholinergic and dopaminergic systems interact strongly we evaluated the expression of D2-subtype dopamine receptor (DA D2) and mAchR together after CT. Animals trained from 30 to 37 days of age and sacrificed 2 mont...
