Bayesian brain

Before psychedelic therapy for wartime trauma, there was narcosynthesis It was called narcohypnosis or narcosynthesis. In essence, this involved the use of potent sedatives — especially sodium pentothal and sodium amytal — to put patients in a prolonged dream-like state. Psychiatrists of the era hoped that this would allow them to process, or “synthesize,” trauma from repressed memories of violence or conflict.

New research provides evidence for conscious awareness during cardiac arrest, in the absence of clinical signs of consciousness.

placebos can work even if a patient knows they are getting a placebo the best explanation for the results of open-placebo trials suggests that, for certain illnesses where the brain amplifies symptoms, engaging in a healing drama can nudge the brain to diminish the volume or “false alarm” of what’s called central sensitization — when the nervous system overemphasizes or amplifies perceptions of discomfort. This mostly involves nonconscious brain processes that scientists call “Bayesian brain,” which describes how the brain modulates symptoms up
or down […] Considerable evidence also shows that placebos, even when patients know they are taking them, trigger the release of neurotransmitters like endorphins and cannabinoids and engage specific regions of the brain to offer relief. Basically, the body has an internal pharmacy that relieves symptoms.

at some level of heat and humidity, the human body can no longer cool itself and its internal temperature rises uncontrollably. […] Past research found that transfer of heat could no longer occur at 35 degrees Celsius (95 Fahrenheit) on what is known as the wet bulb temperature scale […] But, in a study published last year, the Penn State researchers found that threshold to be closer to a wet bulb temperature of 31 degrees Celsius (88 Fahrenheit) for a sample of young and healthy research subjects who were not accustomed to such muggy conditions.

the MP3 technology became patent-free in the United States on 16 April 2017 when U.S. Patent 6,009,399, held by and administered by Technicolor, expired. […] AAC and other newer audio codecs can produce better quality than MP3, but the difference is only significant at low bitrates (2017)

Our data therefore provide strong evidence that when some (but not all) people flip a fair coin, it tends to land on the same side it started
