Arc protein expression is not preferentially increased in adult-born, <5-week-old granule cells after acquisition of the APA task. (A) Schematic representation of the experimental approach. (B–D) Representative images of BrdU+ cells (green), Arc+ cells (red), and a BrdU+/Arc+ cell (white arrow) in the dentate granule cell layer. All cells are labeled with the nuclear stain DAPI (blue). Scale bars represent 50 µm; n = 4–5.
