Figure 3

(A) The proportion of Arc mRNA-positive cells is significantly higher in dorsal CA3 pyramidal cells (22% +/− 1.8) compared to more ventral CA3 pyramidal cells (8.1% +/− 0.9). (B) Representative confocal images from dorsal and (C) ventral CA3 hippocampal subregions, respectively. Calibration bar = 20 µm. Cell nuclei are counterstained with Sytox shown here in green and Arc mRNA positive Foci are in red. The insets in B and C show a magnified view of the Arc transcription foci in CA3 pyramidal cells in the dorsal and more ventral areas respectively. The white arrows correspond to the same cell in the main image and the magnified image.
