Fig. 2.
Dopamine, GABA, and glutamate concentration in the NAc after various doses of i v carbamathione. Perfusion of NAc was initiated 60 min before the i v administration of carbamathione (t = 0). Microdialysis samples were collected every 3 min for neurotransmitter analysis. The basal concentrations of dopamine, GABA, and glutamate in microdialysis samples from the NAc were 7.4 ± 1.8 nmol/L, 63.5 ± 11.7 nmol/L, and 2.9 ± 0.5 µmol/L, respectively. Data shown as a percent of baseline (± SEM; n = 5). See Table 1 for statistical analysis.
