Egr1 in area CA1. A. Basal levels of Egr1 mRNA are higher in adult rats (n=3) relative to aged rats (n=3), as measured by RT-PCR (*p = 0.023). B. The proportion of pyramidal neurons that transcribe Egr1 under resting conditions, are similar in adult and aged rats (p > 0.05). C. Representative confocal images from control rats in both age groups for area CA1. D. Behavior-induced levels of Egr1 mRNA are not different between adult (n=6) and aged (n=6) rats, as measured by RT-PCR (p > 0.05). E. The proportion of CA1 pyramidal neurons that transcribe Egr1 after exploration are similar in adult and aged rats (p > 0.05). F. Representative confocal images from CA1 of behavior-treated rats in both age groups. Green = Egr1, Blue = cell nuclei stained with TOPRO. Magnification = 40×. Scale bar = 20 µm.
