Figure 1. EPM performance in 3.5 month old control and rapamycin-treated OXYS rats and control Wistar rats. Treatment (0.1 or 0.5 mg/kg?day rapamycin) was started at the age of 1.5 months. OXYS rats had reduced the number of entries to open arms (A), time spent in open arms (B), frequencies of rearing (C), and increased grooming frequency (D) in comparison with Wistar rats. In rapamycin-treated OXYS rats, the of rearing was increased. Legend: #p < 0.05 as the difference between the rat strains and *p < 0.05 as compared of Rapamycin-treated to the control OXYS rats.
