Fig 1: Characterization of sleep/wake behavior in juvenile Long-Evans rats

(A) Two example sleep/wake histories from two different animals. Y axis is a moving mean showing percent of time spent awake in the previous 4 hours; x axis is zeitgeber time (ZT) in hours. Periods where the animal is in a sleep dense epoch (>65% time asleep in previous 4 hrs) are colored blue, while >65% wake in previous 4 hrs are colored green. Red arrows indicate points showing differing sleep/wake dense experiences between animals at the same ZT. (B) Average percentage time spent awake in the previous 4 hours as a function of ZT time. Light green shading indicates the standard deviation between animals; n = 30 animals. (C) Normalized delta power from the EEG of animals in B as a percent of baseline (hours 7-11 in the light period). Shading represents SEM between animals. (D) Average time spent in each behavioral state shown as a proportion for each animal broken down by light period (left) and dark period (right); each point represents one animal. Mean and SEM shown, n = 30 animals.
