TL;DR: Two experiments report the existence of waking ultradian rhythms in the flow of urine which are analogous to the REM-nonREM cycles in waking subjects in physiological, endocrine and psychological processes.
Abstract: THERE is evidence that neural oscillators may regulate the flow of urine, Mandell et al1 demonstrated ultradian rhythms in urine flow in catheterised patients during sleep, synchronised with the sleep REM-nonREM cycles (REM, rapid eye movement) They attributed these rhythms to rhythmic secretion of antidiuretic hormone (ADH) during sleep Others have demonstrated episodic secretion of ADH during sleep but no correlation with REM-nonREM cycles2 Reports3–10 of ultradian rhythms of 90–100 min analogous to the REM-nonREM cycles in waking subjects in physiological, endocrine and psychological processes, suggested the existence of waking ultradian rhythms in the flow of urine We report here two experiments which demonstrate these rhythms

TL;DR: Thirty subjects tests on the SAE for 8 hrs during morning and evening periods demonstrated significant ultradian rhythms in perception that were nonstationary with respect to the frequency of the rhythms and the level of the illusion.
Abstract: Thirty subjects tests on the SAE for 8 hrs during morning and evening periods demonstrated significant ultradian rhythms in perception. The perceptual rhythms were nonstationary with respect to 1) the frequency of the rhythms reflected in some slowing of the rhythms during the course of the testing period, and in frequency differences between the morning and afternoon rhythms, and 2) the level of the illusion reflected in abrupt shifts in the magnitude of the SAE during the course of the testing period without subsequent recovery.
