Fig. 2.

Actigraphy data for three admissions for a mixed state (case 2). a, b Represent the first recording (R1); c, d the second recording (R2) and e, f the third recording (R3). Time of day is shown at the bottom of each chart (24-h clock). Light grey parts at the beginning and end of each chart represent non-monitoring time; a, c, e are 24-h actograms: activity counts are shown as black, vertical lines on a scale from 0 to 500 counts. One square in the grid represents 1 h on a horizontal axis and 125 counts on a vertical axis. b, d, f The ratio between rest and activity as the fully drawn line (left axis) and sample entropy as the dotted line (right axis)
