Increased locomotor activity in nNOS KO mice. (A-D) Open field test: total distance traveled (A), stereotypic behavior (B), vertical activity (C), and time spent in the center of the compartment (D) were recorded. (E-H) Light/dark transition test: distance traveled in the light/dark compartments (E), number of light/dark transitions (F), time spent in light compartment (G), and latency to enter the light compartment (H) were recorded. (I-L) Elevated plus maze test: number of arm entries (I), percentage of entry into open arms (J), distance traveled (K), and time spent on open arms (L) were recorded. The p values indicate genotype effect in two-way ANOVA.
