Mean DI’ for sham-control and irradiated rats on the social odor recognition memory task.

<p>Data are shown for sham-irradiated control (patterned bar) and 2.3 Gy X-ray exposed rats (black bar) on the habituation day (Day 1, left panel) and on the recognition test day (Day 2, right panel). Irradiated and control rats performed similarly on the Day 1 Habituation trials and displayed a significant preference for the N1 bead on Trial 1, compared to no preference for the N1 bead on Trials 2 and 3. While an increase in DI’ is apparent for the irradiated rats on Trial 3 during the Day 2 Recognition Test, this increase was not significant. *Denotes significant difference, alpha = 0.05.
