This increase in brain activity near death was detected in the 'posterior cortical hot zone.'
The team studied four dying patients in intensive care after their life support was turned off due to ineffective treatment. The researchers examined the second-by-second records of these patients as they were being monitored with an electroencephalogram ., which is known to be the fastest brainwave and mainly occurs when an individual is conscious. Both of these patients were women.This increase in brain activity near the point of death was detected in the "posterior cortical hot zone.
The team does not know why only two patients experienced a surge in brain activity while the other two did not. Furthermore, it is impossible to determine whether the surge was related to possible visions in the final moments. The team hopes to collect more data in order better to understand brain activity in the final moments of life.The brain is assumed to be hypoactive during cardiac arrest. However, animal models of cardiac and respiratory arrest demonstrate a surge of gamma oscillations and functional connectivity.
