Figure 2. Kcna1−/− mice exhibit defects in post-sigh apnea generation.
(A) Representative plethysmography recordings of the different types of apneas in WT mice. (B) Quantification of apnea frequency by type, (C) apnea duration by apnea type, (D) sigh frequency per hour, and (E) percentage ratio of post-sigh apneas to total number of sighs for WT and KO mice. n=6/genotype. **, P<0.01; ***, P<0.001 (unpaired two-tailed Student’s t test). NA, not available.
