Abstract

Periodicities in physiological activity were examined in young female rats prior to and at puberty. At least three distinct periodicities in these data were observed: (i) light: dark differences in the occurrence of wakefulness (W) and quiet sleep (QS); (ii) a 90-min cycle between behavioral sleep and wakefulness; and (iii) a 10 to 20-min rhythm possibly reflecting an active sleep cycle. These periodicities included changes in EEG and EMG amplitude, somatic activity, heart rate, and variability in heart rate. The changes in sleep-waking states at puberty (either spontaneous or precociously induced) did not result in any marked changes in either the 10 to 20-min or 90-min rhythms.
