FGF-2 mRNA integrated density (percent of NS control) in subregions of the mPFC in rats exposed to escapable (ES) or inescapable stress (IS) and no stress controls (NS) at 0, 2, 24, and 72 hr after termination of the stress session in the anterior cingulate (a), prelimbic (b), and infralimbic (c) regions. FGF-2 mRNA expression increases in a time- and region- dependent manner in the mPFC after ES or IS. ES produced a faster (increased at 0 hr in all regions compared to NS) and greater increase of FGF-2 mRNA in subregions of the mPFC than did IS.
# greater than NS, p < .05
* greater than IS, p < .05
