Your brain hallucinates your conscious reality | Anil Seth

  • Published: 18 July 2017
  • Right now, billions of neurons in your brain are working together to generate a conscious experience -- and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen? According to neuroscientist Anil Seth, we're all hallucinating all the time; when we agree about our hallucinations, we call it "reality." Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence.

    There is more Sci-Fi in it. The body (that means the brain, too!) is part of our by conciousness computed reality. And conciousness is fundamental not this reality. That is what quantum mechanics experiments try to tell us for about 100 years meanwhile. There is no objective reality when our basic „pixels“ are just statistical potential of particles. Time to wake up from all kinds of scientific AND religious beliefs.

      Anil is a Kantian MORON - - this stuff isn't that confusing. His philosophy is messed up, so he is clueless and makes a fool of himself.

                            This is so wrong... the brain is not creating consciousness. If that is true, how can people be conscious when there is no brain activity like with Near Death Experiences?

                                  I can't help but laugh when these materialists paint such a barren, mechanistic picture of the world, then grin and say it's all good because of "muh scientific wonder". Most people are not fired up by theories and charts, they want purpose, meaning and telling them life is just an illusion and death is annihilation doesn't exactly help. Even if spirituality is just an evolutionary adaptation, it's a damn good one and you shouldn't abandon it out of intellectual vanity, just like you shouldn't throw away your torch in the dead of night just because you think you have the terrain figured out.

                                    Humans are Dual beings - when we say "my body" or we say "my spirit" we are referring to parts of ourselves. Our spirit and body combined comprise our soul. The worth of the soul is it's capacity to become eternal perfected exalted beings. Like God our spirits divine father. We (our spirits) are here to obtain physical bodies and learn to master their human natural tendencies which are inherently ignorant, the opposite of intelligence, or in other words the natural man is evil, an enemy to God. Our spirit manifests into this physical reality first in the form of thought, then word, then action. Words are complex expressions of the energy of our souls intelligence and actions are how we, sons and daughters of God, create our lives. If you wish to know more. Start praying to God. He and his companion, are a God of Love and they Love you and will hear and answer your prayers and lead you and guide you and walk beside you and help you find your way through this mortal experience and back once again to their eternal perfected glorified brilliant divine embrace. Our loving Heavenly Parents.

                                                        CHeckerboard illuison is not an ilusion, its a phenomenon thar really happens. It's some kind of compensation circuit. It makes the A and B squares to look subjectively different, but not by as traditional explanation. There is an actual luminance corrector somewhere inside the vision pathway. You really are seeing the A and B in different shades of gray. The effect pops inmediately when using the vertical bars to compare the two squares. If you look closely to the bars int he image on the right (5:39), you'll realize that they has a gradient of grey along it, being darker in the surrounds of A, and lighter on the surrounds of B. this gradient is not from the image itself, but generated for the compesnation circuits along the visual pathway. To see the gradient clearly you must fix your gaze on the letter A and try to focus your attention around B but without moving the gaze from A. You can see that around B, the bands get lighter in a very very soft gradient.

                                                                          Click bate title on a fairly fascinating talk.
                                                                          Oh, and his implication that this could revolutionize psychology is silly. Using different phrasing, this knowledge is already fully integrated into psychology. See; exposure therapy, among many many other examples.
                                                                          He could have said so much more if he weren't focused on being flashy. But hey, a standing ovation. Mission accomplished.

                                                                          One of the most important lessons people every learn are lessons they learned wrong.
                                                                          When friends and family explain their problems to you it is usually fairly easy to see were things went wrong right?
                                                                          That is why their problems aren't, your problems.
                                                                          They fear authority? They fear dogs? They think they are WAY funnier than they are? You're sister ALWAYS ends up with losers?
                                                                          They are too busy seeing the world as they have learned to perceived it to see the world as it actually is.
                                                                          We see this everywhere in life.
                                                                          Relearn the lessons. Teach your brain.

They we're two different shades of gray. Which is why you can make out the letter A easily, but the letter B is hazy.
