Table 2. Brain nor-β-CIT binding in the two groups by 5-HTTLPR polymorphism.

		Striatum	Thalamus	Midbrain	Tem (R)	Tem (L)	Midfront
l homozygotes (16)	Mean	2.65	1.09*	1.29	0.27	0.26	0.34
	SD	0.33	0.19	0.12	0.06	0.05	0.1
s carriers (14)	Mean	2.75	1.25*	1.36	0.28	0.27	0.31
	SD	0.28	0.17	0.18	0.09	0.11	0.15

^* = Thalamus 5-HTT binding was slightly lower in l homozygotes compared to s carriers (p = 0.006). Tem (L/R) = left/right temporal region.
