A. Power densities for EEG activity in 1 Hz to 13 Hz band. B. Power densities from 13 Hz to 60 Hz. There were no significant differences between control and KO at any frequency. In A and B, each point is the mean of individual experiments. N=5 for both genotypes. Error bars are standard deviations. C. In each frequency band (delta, theta, alpha, beta, gamma), the average power densities are shown in control (blue bars) and Ndufs4(KO) (red bars). Bar values are the mean power in each of the respective labeled regions in panels A and B. Error bars represent standard deviations. As with values for individual frequencies there were no significant differences in the frequency ranges.
