To assess whether consciousness exists independently of the human brain, people such as Sam Parnia are doing experiments in which images - or electronic devices with images - are placed in locations near the ceiling in hospital rooms where people might be expected to have near death experiences, but are supposedly inaccessible to hospital staff. If there ever is a reported instance in which a patient in such an experiment reports having a NDE and identifies the image correctly, would this one example be sufficient to claim that consciousness exists independently of the human brain?
