Total immobility time during the 5 min session of the forced swimming test (test) shown by animals treated with vehicle (ACSF, open columns) or CoCl 2 (cobalt, filled columns) into the BNST. Intra-BNST injection of CoCl2 (1 mM/100 nL) before pretest or before test reduced immobility time in the rat forced swimming test. Data are expressed as mean ± S.E.M. (n = 5-7/group). * indicates significant difference from respective vehicle-treated group (P < 0.05, Student-t test).
