“…Over the past several years, c-Fos immunohistochemistry has been used to identify neuronal sites activated by ethanol administration. Ethanol-induced c-Fos-like immunoreactivity (cFLI) has been identified in several forebrain regions that include the bed nucleus of the stria terminalis, the paraventricular nucleus of the thalamus and hypothalamus, the central nucleus of the amygdala, and the nucleus accumbens (Chang et al, 1995;Hitzemann and Hitzemann, 1997;Ryabinin et al, 1997;Thiele et al, 1998b;Zoeller and Fletcher, 1994). In the brainstem, ethanolinduced cFLI has been observed in regions that include the lateral parabrachial nucleus (PBN), the area postrema (AP), the locus coeruleus (LC), and the nucleus of the solitary tract (NTS) (Ryabinin et al, 1997;Thiele et al, 1996Thiele et al, , 1997Thiele et al, , 1998b.…”
