<div style="text-align: justify; "><b style="font-size: 1rem;">Near-death experience accounts that include stories of white light, visitation from deceased loved ones, hearing voices, among other characteristics, grab our imagination and are ingrained in our culture.</b><br></div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The fact that these reports have so many similarities makes one wonder if there is something fundamentally real underlying them. It is also possible that those who have survived death are revealing glimmers of a consciousness that persists even after the heart has stopped beating.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">A new study published in the Proceedings of the National Academy of Science, provides early evidence of a surge of activity correlated with consciousness in the dying brain.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The study, led by Jimo Borjigin, Ph.D., associate professor in the Department of Molecular &amp; Integrative Physiology and the Department of Neurology, and her team is a follow-up to animal studies conducted almost ten years ago in collaboration with George Mashour, M.D., Ph.D., the founding director of the Michigan Center for Consciousness Science.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Similar signatures of gamma activation were recorded in the dying brains of both animals and humans upon a loss of oxygen following cardiac arrest.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">"How vivid experience can emerge from a dysfunctional brain during the process of dying is a neuroscientific paradox. Dr. Borjigin has led an important study that helps shed light on the underlying neurophysiologic mechanisms," said Mashour.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The team identified four patients who passed away due to cardiac arrest in the hospital while under EEG monitoring. All four of the patients were comatose and unresponsive. They were ultimately determined to be beyond medical help and, with their families' permission, removed from life support.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Upon removal of ventilator support, two of the patients showed an increase in heart rate along with a surge of gamma wave activity, considered the fastest brain activity and associated with consciousness.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Furthermore, the activity was detected in the so-called hot zone of neural correlates of consciousness in the brain, the junction between the temporal, parietal and occipital lobes in the back of the brain. This area has been correlated with dreaming, visual hallucinations in epilepsy, and altered states of consciousness in other brain studies.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">These two patients had previous reports of seizures, but no seizures during the hour before their deaths, explained Nusha Mihaylova, M.D., Ph.D., a clinical associate professor in the Department of Neurology who has collaborated with Dr. Borjigin since 2015 by collecting EEG data from deceased patients under ICU care. The other two patients did not display the same increase in heartrate upon removal from life support nor did they have increased brain activity.
