Results: GABA uptake inhibitor nipecotic acid-induced increase of MAP was blocked by GABAA receptor antagonist bicuculline, but not by GABAB antagonist CGP 35348;
In midbrain slices from rats treated with saline or a single dose of cocaine, LTP could not be induced in VTA dopamine neurons unless GABA-mediated inhibition was reduced by bicuculline or picrotoxin.
