This results in cataplexy and sleep paralysis, episodes of muscle paralysis when awake, or in the generation of...

Near-Death High-Frequency Hyper-Synchronization in the Rat Hippocampus

Frontiers in Neuroscience July 31, 2019 Yujiao Zhang, Zhenyi Li, J. Zhang et al. 13 citations

Near-death experiences (NDE) are episodes of enhanced perception with impending death, which have been associated with increased high-frequency (13–100 Hz) synchronization of neuronal activity, which is implicated in cognitive processes like perception, attention and memory.
