Brain death or brain dying?
For the past 50 years, the medical profession has understood ‘‘brain death’’ to represent the endpoint of a neuropathologic vicious cycle. An initial major brain injury sets off a mutually exacerbating cascade of cerebral edema, increased intracranial pressure, and decreased cerebral blood flow, which advances beyond some point-of-no-return to a state of no cerebral blood flow and total brain i...
متن کاملNear death experiences (NDEs): The dying brain
There is a growing perception that the existence of near-death experiences (NDEs) poses a serious challenge to current scientific understandings of the brain, mind and consciousness (Braude, 2003; Fenwick & Fenwick, 1995; Parnia & Fenwick, 2002; Parnia, Spearpoint & Fenwick, 2007; Parnia, Waller, Yeates & Fenwick, 2001; Ring, 1980; Sabom, 1998, 1982). This was reaffirmed recently in a high-impa...
متن کاملSurge of neurophysiological coherence and connectivity in the dying brain.
The brain is assumed to be hypoactive during cardiac arrest. However, the neurophysiological state of the brain immediately following cardiac arrest has not been systematically investigated. In this study, we performed continuous electroencephalography in rats undergoing experimental cardiac arrest and analyzed changes in power density, coherence, directed connectivity, and cross-frequency coup...
متن کاملSurge of neurophysiological activity in the dying brain.
Borjigin et al. (1) describe recordings from electrodes implanted in rat brains that were made during and after cardiac arrest in rats. The surprising and unexplained 30-s surge in electrical coherence and connectivity certainly merits further study, but the authors’ suggestion that this transient electrical surge has implications for near-death experiences in humans seems premature to us. Firs...

His original work is deservedly much esteemed. It has lost nothing by presentation in this volume together with additional information on the circumstances, customs and attitud...
