Abstract
The “biologic clock” found in all organisms accounts for such well-known phenomena in man as the variations over a 24-hour period in hormone secretion, temperature, and many other body functions, as well as jet lag. It has been found that periodic factors in the environment, like light and dark, pace the biologic rhythm but do not act as its immediate cause. Rather, the rhythm seems to be inherent in the organism.

Social cues are sufficient to entrain human circadian rhythms, and absence of light has no immediate effect on the functions measured.

The paper describes the properties of biological, self-sustained oscillators under constant conditions as well as under the influence of a synchronizing environmental rhythm, the multiplicity of rhythmic functions in an organism, and cases of internal desynchronization in man.
