First Evidence For Higher State of Consciousness Found (neurosciencenews.com)

New submitter baalcat quotes a report from Neuroscience News: Neuroscientists observed a sustained increase in neural signal diversity -- a measure of the complexity of brain activity -- of people under the influence of psychedelic drugs, compared with when they were in a normal waking state. The diversity of brain signals provides a mathematical index of the level of consciousness. For example, people who are awake have been shown to have more diverse neural activity using this scale than those who are asleep. This, however, is the first study to show brain-signal diversity that is higher than baseline, that is higher than in someone who is simply "awake and aware." Previous studies have tended to focus on lowered states of consciousness, such as sleep, anesthesia, or the so-called "vegetative" state. For the study, Michael Schartner, Dr Adam Barrett and Professor Seth of the Sackler Center reanalyzed data that had previously been collected by Imperial College London and the University of Cardiff in which healthy volunteers were given one of three drugs known to induce a psychedelic state: psilocybin, ketamine and LSD. Using brain imaging technology, they measured the tiny magnetic fields produced in the brain and found that, across all three drugs, this measure of conscious level -- the neural signal diversity -- was reliably higher. The findings have been published in Scientific Reports.

I remember seeing an interview with an artist who tried using psychedelic drugs. Under the influence, he made the most beautiful painting, with amazing colors and structure and profound meaning. He was soo amazed at the depth of his perception, and creativity.

The next day, when he was sober again, he looked at the painting, and noticed he had painted the whole sheet muddy brown.

You are cut off from using the word "logical" until further notice.
