摘要：

The cerebral cortical EEG, quantified as an index, the percent-time delta, accurately indicated the behavioral state of young caimans regarding the arousal-sleep continuum. Quiet sleep, accompanied by high voltage slow EEG, behavioral quiescence, characteristic posture, elevated arousal threshold and rapid state reversibility with intense stimulation, occupied 12.7% of 24 h periods of young caimans. Rapid transition between wakefulness and sleep, frequent locomotion and changes of posture were observed; active sleep was not observed. Effective thermoregulation resulting in natural, preferred body temperature may be essential for full expression of sleep behavior. Behavioral sleep marked by slow wave activity in the cerebral EEG is suggested to be phylogenetically ancient, possibly present in the archosaurian ancestor of birds and crocodilians.
