Peak frequency and minute ventilation. A) Average frequency-modulated (FM) peak frequency (kH) + standard error of the mean (SEM). Wildtype (WT) = white bar, Pink1−/− = gray bar, n = 10 per genotype. Statistical significance is denoted an asterisk: ***p < 0.001. B) Pearson correlation between minute ventilation ($\dot{\mathrm{V}}\mathrm{E}$/100 g) and average FM peak frequency. Red line denotes significant correlation. Open circles = WT, black circles = Pink1−/−.
