Histograms of bout durations of each state in units of number of 4-s epochs. Duration is given on the x-axis and probability on the y-axis. (a)–(c) Give the bout durations for C57 for REM, NREM, and WAKE; (d)–(f) give the bout durations for AJ; (g)–(i) give the bout durations for DBA; (j)–(l) give the bout durations for PWD.
