Summary When rats were kept in continuous light there was a time-lag between the onset of activity arrhythmia and that of persistent estrus. When animals showing both arrhythmias in continuous light were kept under a LD 21∶3 photoperiod, the activity rhythm returned to normal but the estrous cycle did not.
