University of Michigan Study Reveals Gamma Wave Surge in Dying Rat Brains, Suggesting Link to Near-Death Experiences
A 2013 study conducted by researchers at the University of Michigan, led by Jimo Borjigin, discovered that the brains of rats exhibited a surge of high-frequency gamma waves in the moments following cardiac arrest. This unexpected finding was observed when electrodes were placed in the cortices of laboratory rats, revealing a burst of gamma oscillations that were more coherent than those seen during normal waking states. The study, published in a major scientific journal, has become a focal point in the field of dying-brain neuroscience. The researchers propose that this gamma surge could be the neural basis for the vivid imagery reported by survivors of near-death experiences. The study has sparked further research and debate about the mechanisms underlying these experiences, with some suggesting that similar processes could occur in human brains during cardiac arrest.
