abstract：:Sulphated cholecystokinin-8 (CCK-8) given into the neostriatum of the rat by in vivo microdialysis produced a concentration-dependent (1-100 microM) increase in extracellular aspartate (Asp) and dynorphin B (Dyn B), but not in glutamate, GABA or dopamine levels. The increase in Asp levels produced by 10 microM CCK-8 w...
