How Near-Death Experiences Arise in the Brain?
Briefly

The process of dying is shrouded in mystery, particularly in terms of near-death experiences (NDEs), which 5-10% of people report. Common themes of NDEs include sensations of detachment from the body, moving through a tunnel, encountering deceased individuals, and experiencing deep peace and wisdom. Recent research by a group led by Charlotte Martial details a comprehensive neuroscientific model explaining the conditions that lead to NDEs, which was constructed from extensive study reviews and aimed at understanding this enigmatic aspect of consciousness. Hypotheses include an evolutionary perspective on their occurrence.
Many people describe these memories in crisp detail and say that they felt more real than real, raising questions about how consciousness generates such experiences.
Martial and her colleagues' model lays out a step-by-step hypothesis for the conditions that give rise to NDEs, proposing an evolutionary theory for why these experiences occur.
