Scientific pitch, also known as philosophical pitch, Sauveur pitch or Verdi tuning, is an absolute concert pitch standard which is based on middle C (C 4) being set to 256 Hz rather than approximately 261.63 Hz, [1] making it approximately 31.77 cents lower than the common A440 pitch standard.
He also, at fans' suggestions, tuned his piano to 432 Hertz (as opposed to the usual 440 Hertz), a frequency believed to help brain waves to relax. [ 60 ] [ 61 ] Riopy uses various compositional techniques in pursuit of his goal to create immersive meditation music that can improve mental health and wellbeing, including using binaural beats ...
Slow-wave sleep (SWS), often referred to as deep sleep, is the third stage of non-rapid eye movement sleep (NREM), where electroencephalography activity is characterised by slow delta waves. [ 2 ] Slow-wave sleep usually lasts between 70 and 90 minutes, taking place during the first hours of the night. [ 3 ]
A new study offers an explanation as to how deep sleep — also known as slow wave sleep — helps support the formation of memories in the brain, which could help with preventing dementia.
In most animals, slow-wave sleep is characterized by high amplitude, low frequency EEG readings. This is also known as the desynchronized state of the brain, or deep sleep. In USWS, only one hemisphere exhibits the deep sleep EEG while the other hemisphere exhibits an EEG typical of wakefulness with a low amplitude and high frequency.

Parents everywhere will be able to relate to this daddy gorilla trying to get his baby to go to bed at Zoo Atlanta, since we've all been in the same boat many times before.
[37] [30]: 57–59 In other words, if at the end of a phase of deep sleep, the organism's thermal indicators fall outside of a certain range, it will not enter paradoxical sleep lest deregulation allow temperature to drift further from the desirable value. [30]: 45 This mechanism can be 'fooled' by artificially warming the brain. [30]: 61
