Relative abundance of CRF-mRNA in the central nucleus of the amygdala (ACe) of 9–10-day-old rats following a single or repeated exposure to cold stress. Hybridization signal for CRF-mRNA was analysed in the ACe of rats sacrificed under stress-free (SF) conditions or rats subjected once (1×) or three times (3×) to cold stress 4 h prior to sacrifice (see materials and methods). Repeated stress resulted in a significant increase in CRF-mRNA expression in the ACe (*P<0.01) compared with SF controls. Each bar represents the mean (standard error of the mean of 17–30 samples from 4–6 brains per group.
