Average percentage of neurons containing the studied substances tested in different experimental groups

		FB+
		NPY+/TH+	NPY+/TH-	NPY−/TH+	NPY−/TH−
Control group	Average (%)	1.91*	62.17*	2.34*	33.58*
	SEM	1.65	2.63	2.02	1.86
RTX	Average (%)	39.6*	43.37*	4.18*	12.84*
	SEM	1.69	1.54	1.02	2.61
TTX	Average (%)	47.3*	10.15*	30.19*	12.35*
	SEM	3.23	0.60	1.69	2.13

Data are shown as the averages ± SEM for the three data points per group. The significance of differences was estimated using the Duncan's test. The statistical significance was evaluated between the neuronal group presenting the same neurochemical characteristics
