In estimating, by use of cosinor-test, the 12- and 24-h component parameters of body temperature circadian rhythm in monkeys under ultradian schedules of lighting and feeding (LD 6:6; DL 6:6) we have shown that an intensive 12-h component is registered in both cases. The presence of a 24-h component of circadian rhythm depends on the zeitgeber phase. This component is present in LD 6:6 (lighting hours 07:00-13:00 and 19:00-01:00) and is absent in DL 6:6 (01:00-07:00 and 13:00-19:00). We hold that the most satisfactory explanation of the phenomena observed is that 12-h component is the result of a masking effect induced by the 12-h schedule (exogenous component) whereas the 24-h component reflects the intrinsic pacemaker work (endogenous component). It should be noted that in our case the masking effect in body temperature rhythm is circadian phase-dependent.
