Figure 7. Anxiety-related behavior is enhanced in Ndufs4 cKO mice in the elevated plus maze test.

(a) Representative activity traces from a control and an Ndufs4 cKO mouse in the elevated plus maze test. C, closed arm; O, open arm. (b) Time spent in closed arms of an elevated plus maze. (c) Time spent in open arms of an elevated plus maze. (d) Number of entries to the open arms of an elevated plus maze of 9-month-old mice. (e) Number of entries to the open ends of an elevated plus maze of 9-month-old mice. *p < 0.05; **p < 0.01; n.s. not statistically significant.
