Only associative CS–US pairing alters gene expression. The relative levels of expression of mRNA (in arbitrary units ± SEM) are shown for regions in which there is no change (first region shown) or in regions with significant change for each of the indicated genes. Gene expression was analyzed at the 2 hr time point after light-shock associative learning (Paired Lgt-shk, black bars), unpaired presentations of lights and shocks (Unpaired Lgt-shk, hatched bars), or shock only controls (Shock Only Ctrl,white bars). ∗∗p ≤ 0.01, ∗p ≤ 0.05 with ANOVA.
