How Channelers’ Brains Work
A new study of channelers has found that areas of the brain associated with language and activity close down when they are engaged in channeling. This means that the part of the brain that forms words is not in use during the channeling process, lending credibility to the notion that they are obtaining the words that they are speaking or writing down from an unknown source that is either in the brain, or is outside of the individual altogether.
During a trance-like session of psychography, experienced mediums in Brazil allow themselves to become receptive to spirits or dead souls. Then they write automatically, channeling the voices of those they believe to be speaking to them.
