  2. Biorhythm (pseudoscience) - Wikipedia

    en.wikipedia.org/wiki/Biorhythm_(pseudoscience)

    Charting biorhythms for personal use was popular in the United States during the 1970s; many places (especially video arcades and amusement areas) had a biorhythm machine that provided charts upon entry of date of birth. Biorhythm programs were a common application on personal computers; and in the late 1970s, there were also handheld biorhythm ...

    Wilhelm Fliess (German: Wilhelm Fließ; 24 October 1858 – 13 October 1928) was a German otolaryngologist who practised in Berlin. He developed the pseudoscientific theory of human biorhythms and a possible nasogenital connection that have not been accepted by modern scientists.

  6. Circadian clock - Wikipedia

    en.wikipedia.org/wiki/Circadian_clock

    In vertebrates, the master circadian clock is contained within the suprachiasmatic nucleus (SCN), a bilateral nerve cluster of about 20,000 neurons. [10] [11] The SCN itself is located in the hypothalamus, a small region of the brain situated directly above the optic chiasm, where it receives input from specialized photosensitive ganglion cells in the retina via the retinohypothalamic tract.

    Overview, including some physiological parameters, of the human circadian rhythm ("biological clock").. Chronobiology is a field of biology that examines timing processes, including periodic (cyclic) phenomena in living organisms, such as their adaptation to solar- and lunar-related rhythms. [1]

    The SCN is then able to influence the sleep wake cycle, acting as the "apex of a hierarchy" that governs physiological timing functions.
