Researchers at Thomas Jefferson University and the University of Sao Paulo in Brazil analyzed the cerebral blood flow (CBF) of Brazilian mediums during the practice of psychography, described as a form of writing whereby a deceased person or spirit is believed to write through the medium's hand. The new research revealed intriguing findings of decreased brain activity during mediumistic dissociative state which generated complex written content. Their findings will appear in the November 16th edition of the online journal PLOS ONE.
The 10 mediums—five less expert and five experienced—were injected with a radioactive tracer to capture their brain activity during normal writing and during the practice of psychography which involves the subject entering a trance-like state. The subjects were scanned using SPECT (single photon emission computed tomography) to highlight the areas of the brain that are active and inactive during the practice.......
