Figure 5.

Animals were divided into two groups based on a median split of performance in the Post-CS period during the retrieval test. High freezers were designated as unimpaired, whereas low freezers were designated as impaired. Panels (A–F) show pRpt6 reported as a percentage (mean, SEM) in 3-month-old animals. Impaired animals showed less pRpt6 than unimpaired in both the mPFC (A) and the RSC (B). As before, there were no differences in the DH (C). Impaired memory performance corresponded with a trend toward a decrease in the VH (D). No differences between unimpaired and impaired animals were observed in the LA (E) or the vlPAG (F). Asterisks indicate p < 0.05; pound signs indicate p < 0.10. White dots represent individual rats.
