Total motor horizontal activity during 5 min of test in an open field arena (a) and total immobility time during 10 min of FST (b) in male and female rats administered with a single intranasal (i.n.) dose of LPS (100 μg/rat) (n = 24) or with 2 i.n. instillations of LPS (100 μg/rat each day) in 2 consecutive days (n = 24) or with respective volumes of control saline solution (n = 24). The animals were tested 24 h after the single dose or 24 h after the second dose respectively. Values are means±SEM. **Significant differences with respect to control saline conditions (**p<0.01).
