The Intense Brain Activity of Dying People Unveiled by Scientists.

A new study published in the journal PNAS has found that the brains of dying humans experience a surge of activity that resembles being awake, even after the person stops breathing. The study tracked four people who were dying due to cardiac arrest as they were taken off their ventilators, and found that two of them had a rush of gamma waves, which are some of the fastest brain waves you can experience. The study authors explained that these gamma waves could mean that patients experienced some form of consciousness, similar to being in a lucid state. However, researchers noted that because the patients did pass away, it is unclear exactly what they experienced as they were dying and if this brain activity even relates to death at all.
