Figure 3

Overview of sleep structure in 24-hour recordings. (a) Plot of all sleep and wake 10-second epochs throughout the 24-hour recordings (numbered columns). Columns 1–10 show recordings from 10 normal rats (1 recording from each rat). Columns 11–17 show recordings from 5 HP rats (columns 11-12 and columns 13-14 show consecutive 24-hour periods from two HP rats, resp.). The top of the y-axis shows the beginning of the day when the lights were turned on. (b) Plot of hourly average sleep (combined NREM and REM) percentages across the entire 24 hours (error bars show SEM). (c) Percentages of epochs in NREM, wake, or REM states (colors and column labels are identical to (a)). (d) Number of epochs in different sleep states (* P < 0.05, two-sided t-test between normal and HP rats; colors are identical to (a)).
