Activity in the elevated plus maze (EPM). Animals in the No Social–Stress group spent significant less time in the open arms of the apparatus, indicative of heightened general anxiety, which was prevented with social stimulation (top). The No Social–Stress group spent significantly less time in the near open arms of the EPM relative to the No Social–No Stress group. This effect was prevented with social stimulation (middle left). Both Social groups spent significantly more time in the far open arms of the EPM relative to both No Social groups (middle right). Both Social groups demonstrated significantly greater movement on the EPM relative to No Social controls (lower right). Social produced significantly more head dips on the EPM compared to the No Social groups (lower right). *P < 0.05 relative to No Social/No Stress. ^# P < 0.05 relative to Stress/No Social. Data are presented as mean ± SEM.
