Plethysmographic in vivo recordings. (A) Plethysmographic in vivo recordings of wild type (WT; n = 9), Htr5b−/− (n = 7), Mecp2−/y (n = 10) and Mecp2−/y;Htr5b−/− (n = 11) mice at postnatal day 40 (P40). Recordings revealed improved breathing in Mecp2−/y;Htr5b−/− mice, which was expressed by the (B) reduction of long (>1 s) apneas, (C) respiratory frequency and (D) irregularity score (IS). Corresponding bar diagrams represent the mean value and standard error of the mean (SEM). Asterisks indicate significance (*P < 0.05, **P < 0.01; Kruskal-Wallis test with Dunn’s multiple comparisons).
