Fig. 5From: Knockout of the circadian gene, Per2, disrupts corticosterone secretion and results in depressive‐like behaviors and deficits in startle responsesEffect of genotype on behaviors in the Forced Swim Test measured during the inactive period. Per2−/− mice a spent less time mobile (struggling/swimming) and b more time immobile (floating) compared to WT mice. *p < 0.05 WT vs. Per2−/− mice. (n = 12 per group)Back to article page
