The amplitude of AVP expression in the SCN is decreased by long day photoperiods. Double-plotted rhythms of PER2 and AVP expression measured in the SCN with immunohistochemistry. White and black bars on the abscissa represent lighting conditions. n = 4–8/time-point/photoperiod. *LD12:12 versus LD20:4, LS Means Contrasts, P <0.006. Cosinor analyses of PER2 and AVP rhythms are in Additional file 1: Table S4
