Several theories exist regarding the phenomenon of Near-Death-Experiences (NDE). There is a huge controversy on the thought that consciousness can survive death or not. However, many scientists as (Berk, 51), put forward the view that currently researches are underway to provide evidence about existence of consciousness outside body.
Considering the Dying Brain Theory of afterlife by Dr. Susan Blackmore, the NDEs are depicted as real. It holds the fact that all individuals with NDEs moves towards a light through similar stages on a spiritual journey irrespective of their differences in culture and ages (Atwater, 42). However, the same aspect also provides evidence for the argument considering NDEs as unreal. Scientifically, the dying function of human brain is same irrespective of ages and cultures. It explains the depiction of similar core elements of all NDEs due to shutting down of the neurotransmitters of brain thus producing the same kind of illusions in all people with NDEs.
An overlap of the two eminent approaches toward NDEs is evident. The two approaches are psychological one identifying the reasons for NDE behaviors and the other is the straightforward physiological approach identifying the brain portion that causes the NDEs due to malfunction (Tassell-Matamua, 260). Evidences show a resentment of accepting the view that NDEs are just a reaction of the initiation of brain death. It is majorly evident in persons having NDEs. However, evidences as people experiencing different responses in their NDEs lay a cloud of doubt to the view of considering NDEs as just a brain function.
