GABA modulates the release of dopamine and acetylcholine from rat caudate nucleus slices

The effects of GABA on depolarization-induced (26 mM K +) release of radiolabeled dopamine (DA) and acetylcholine (ACh) from slices of rat caudate nucleus were examined with a superfusion method. GABA, in concentrations of 10 −5–10 −3 M, dose-dependently enhanced the release of DA, either accumulate...
