Extracellular DOPAC, DA and HVA basal levels in the mPFC of rats

	DOPAC (nM)	DA (nM)	HVA (nM)
Dialysis values (ACSF group)	25.85 ± 7.94	1.41 ± 0.35	115.41 ± 22.76
Dialysis values (GABAzine group)	56.69 ± 6.58	1.37 ± 0.69	132.76 ± 34.76
Mean Probe recovery (%)	12.0	14.1	11.4
Basal values (ACSF group)	215.42 ± 66.17	10.00 ± 2.48	1012.37 ± 119.65
Basal values (GABAzine group)	472.42 ± 54.83*	9.71 ± 4.89	1164.56 ± 304.91

Data shown are the mean ± SD. We obtained the probes recovery by using 3 mm membrane length and at the 2 ul/min flow rate. Basal values = dialysis values/mean probe recovery. Significant difference between GABAzine- and ACSF- treated rats;
