“In contrast to atropine (40.0 mg/kg), which increased the uptake … in synaptosomes from both the rat hippocampus and striatum, the administration of phencyclidine (54.4 mg/kg), 30 min prior to …, caused a significant decrease in the uptake of choline in synaptosomes from rat … (but not hippocampus).”
“The data suggest that phencyclidine may be exerting an indirect effect on the uptake of choline in the striatum via its interaction with the dopaminergic system.”
