Performance of rats in forced swim test on pnd 35. Values represent climbing activity (in seconds) during the first 2 and last 2 min of observation (a) and total climbing time within 5-min observation (b). *p  <  0.05 represent significant differences and p ≥ 0.05 represent trend towards differences vs. Control group; ^##p < 0.05, ^###p < 0.001, ^####p < 0.0001—vs. VPA group (Dunnett’s multiple comparisons test). $—0.10 ≥ p ≥ 0.05 represent trend towards differences vs. Control group (Sidak’s multiple comparisons test). Data are presented as box and whiskers plot. N = 11–14 rats/treatment
