In vivo microdialysis studies indicated that systemic or intra - NAc administration of AMN082 significantly decreased extracellular gamma - aminobutyric acid ( GABA ) and elevated extracellular glutamate , but had no effect on extracellular dopamine in the NAc , suggesting that a non - dopaminergic mechanism underlies the effects of AMN082 on the actions of cocaine .
