Electrophysiology

Researchers have made significant strides in understanding the neurological process of dying. Their study reveals that during anoxia, or oxygen deprivation, the brain undergoes a series of changes, including a massive release of glutamate and a surge in gamma and beta waves, potentially linked to near-death experiences. This is followed by a 'wave of death' - a high-amplitude wave marking the transition towards total cessation of brain activity.
