Mean circadian period, amplitude, sine wave goodness-of-fit, and the damping constant of mPer2Luc rhythms of SCN explants from wild-type (black), Cx36+/− (orange), and Cx36−/− (red) mice. Data are shown as mean ± SEM. PERIOD: F2,18 = 0.4747, p = 0.6297, post hoc: not significant. AMPLITUDE: F2,18 = 0.4256, p = 0.6598, post hoc: not significant. GOODNESS OF FIT: F2,18 = 0.2564; p = 0.7766, post hoc: not significant. DAMPING: F2,18 = 0.02619; p = 0.9742, post hoc: not significant. One-way-ANOVA with Bonferroni post hoc test comparing all data sets with each other; wild-type: n = 4; Cx36+/−: n = 10; Cx36−/−: n = 7.
