Sleep intensity of Dα1 knock-out. (A) Mean duration of sleep bouts for every hour of a day. White background: day-time, gray background: night-time. (B) Proportion of population reactive to stimuli based on pre-stimuli immobility time. White background: day-time, gray background: night-time. The longer flies had been immobile, the lower the proportion of flies that would react due to being in deeper sleep state. Wild-type flies generally have lighter sleep ie. more reactive during day-time than night-time. (C) Mean number of sleep bouts during day time across different experiments. All error bars are standard errors of the means. For (A) and (B), control n = 44, knockout n = 38. For (C), experiment 1: control n = 30, knockout n = 32, experiment 1: control n = 32, knockout n = 31, experiment 3: control n = 32, knockout n = 32.
