Abstract: This exploratory study was based on the cognitive and perceptual characteristics of 50 cases of near-death experiences (NDEs) collected through the International Association for Near-Death Studies-France. This study resulted in the formulation of a model of perception based on the concept of "global perception" or "global acquisition of information." Further analysis showed that this model is consistent with the concept that these perceptions are not purely hallucinatory but are, in part, modified perceptions of reality. Several clues are then proposed to explain how this type of information could be processed at the cerebral level and beyond. Finally, we offer a clinical research protocol, including a test that could lead to irrefutable proof of veridical perception during NDEs.
