Michigan Team Detects Gamma Surges in 2 of 4 Dying Human Brains

Summary
Two of four comatose patients taken off life support showed a burst of gamma activity as they died, University of Michigan researcher Jimo Borjigin’s team reported.
The signal was concentrated in the posterior cortical hot zone and resembled synchronized, high-frequency patterns long linked to conscious processing, attention and memory binding.
The finding extends Borjigin’s earlier 2013 rat study, which found a 20- to 30-second gamma surge after cardiac arrest, and a 2022 human case recorded during an epileptic patient’s death.
Not all patients showed the effect, and researchers said medication, prior brain injury or differences in the dying process could explain the split, leaving the mechanism unresolved.
The work sharpens debate over near-death experiences by suggesting some dying brains may briefly become unusually coordinated rather than simply shutting down.
Can a 30-second brain surge explain life reviews and timeless realms, or is something else happening at the moment of death?
If the dying brain has a hidden state of hyper-awareness, are we fundamentally misunderstanding the process of death itself?
Organized Brain Activity at Life’s End: Gamma Waves, Near-Death Experiences, and the Future of Death Definition
Overview
Groundbreaking research from the University of Michigan, led by Dr. Jimo Borjigin, has revealed surprising brain activity at the brink of death. By monitoring comatose patients taken off life support with EEG, scientists detected a surge of gamma waves in the temporo-parieto-occipital junction—an area linked to conscious processing, memory, and problem-solving. This organized brain activity was found in only two out of four patients, making the discovery especially intriguing. These findings suggest that even when patients appear unresponsive, the brain may still show signs of complex activity as life ends, opening new questions about consciousness and the dying process.
