State transition probabilities in the rock hyrax during 24 h based on the data of all 5 animals studied. In most cases SWS was followed by waking, thus making this the most common sleep pathway observed in the rock hyrax. The next most common pathway would be when SWS is followed by SI which then predominantly transitions to waking; however, in some cases it also transitions to REM, which in turn is most commonly followed by waking.
