Figure 8.

Density of staining within Timm-positive contours was not more intense in rapamycin-infused hippocampi. The average optical density (0, no tissue in light path; 1, microscope light source turned off) within Timm-positive contours in three sections within ±200 μm of infusion site and corresponding sections of contralateral noninfused hippocampus for all experimental groups is shown. Within each experimental group, densities of aberrant Timm staining were similar in infused and contralateral, noninfused hippocampi (ANOVA, p = 0.4). Error bars indicate SEM.
