Figure 1.

Relative optical density (ROD) of CART mRNA expression (+/− SEM) in the dentate gyrus of adult and prepubertal rats at baseline and 2 hours after a 30 minute restraint stress. Prepubertal rats showed significantly (F (1,18)=10.66) higher levels of CART mRNA expression than adults, though no effect of stress was observed at either age. Asterix indicates a significant difference between unstressed adult and prepubertal rats (n=6, p<0.05).
