Development Of Circadian Sleep-Wakefulness Rhythm In A Healthy Boy Gauged By Circadian Quotients, Ellen Reeker, Michael Diffley

Journal of the Minnesota Academy of Science

The circadian quotient, briefly CQ, serves to estimate the prominence of a rhythm with a period of about 24 hours. The CQ may be computed from so-called variance spectrum analysis, among other procedures ( 1) . Computational details and some applications have been discussed earlier (1 , 2). We wish to illustrate herein the use of the CQ for gauging the development of a circadian sleep-wakefulness rhythm in the senior author's first-born child, FAR, also documented in general terms, elsewhere ( 3).
