Histograms of state bout durations in units of 4-s epochs conditional on the previous state for C57. Duration is given on the x-axis and probability on the y-axis. (a) Gives the bout durations for REM followed from NREM; (b) is deliberately left empty, i.e., REM following WAKE; (c) gives the bout durations for NREM followed from REM; (d) gives the bout durations for NREM followed from WAKE; (e) gives the bout durations for WAKE followed from REM; (f) gives the bout durations for WAKE followed from NREM.
