Basal concentrations of extracellular dopamine and glutamic acid in the dialysate from the Acb shell of WT, HET and DAT KO rats.

Parameter	Line			One-way ANOVA
	WT (N = 8)	HET (N = 10)	DAT KO (N = 8)	F(2,23)	p
Dopamine (nM)	1.98 ± 0.18	5.27 ± 0.40	18.72 ± 3.64****###	19.38	>0.0001
Glutamic Acid (μM)	0.80 ± 0.12	0.71 ± 0.07	0.59 ± 0.06	1.39	0.2692

****P < 0.0001 vs. WT. ^###P < 0.001 DAT KO vs. HET. One-way ANOVAs followed by Tukey’s pairwise comparisons. Values are means ± SEM of the means of the last four dialysate aliquots of 8/10 rats/group collected before the introduction of the female rat in the mating cage.
