This is not the first time we\u2019ve seen the&nbsp;<a href=\"https:\/\/www.popularmechanics.com\/science\/a35938702\/zombie-genes-come-alive-after-death\/\" target=\"_blank\" rel=\"noreferrer noopener\">brain activity in a dying person<\/a>\u2014some patients who have been pulled off of life support have had simplified EEG recordings taken, though they\u2019ve been limited to frontal cortex signals. This, however, is the first case of detailed recordings that may be able to shed some light on what we experience when we die.<\/p>\n\n\n\n<p>For decades now, people have reported episodes of paradoxical lucidity and heightened consciousness in relation to death. This is intriguing as this seems to be occurring in brain areas that are shutting down in relation to death,\u201d says&nbsp;<a href=\"https:\/\/med.nyu.edu\/research\/parnia-lab\/\" target=\"_blank\" rel=\"noreferrer noopener\">Dr. Sam Parnia<\/a>, director of critical care and resuscitation research at NYU Langone.<\/p>\n\n\n\n<p>Although, in the past, it had been assumed that these may simply be anecdotes, population surveys have indicated that this phenomenon occurs in around 10 percent of the population [suggesting] that around 800 million people are living with this,\u201d Parnia tells&nbsp;<em>Popular Mechanics<\/em>.<\/p>\n\n\n\n<p>The team working with the patient was able to capture about 900 seconds of brain activity and focused most of its analysis on the first 30 seconds before and after the patient\u2019s heart stopped beating.<\/p>\n\n\n\n<p>Immediately following cardiac arrest, they noticed changes in the brain waves involved in higher-order cognitive functions, including information processing, concentrating, memory retrieval, conscious perception, and the different stages of dreaming, possibly indicating the brain was actively engaging in&nbsp;<a href=\"https:\/\/www.popularmechanics.com\/science\/health\/a39611355\/why-do-we-sleep\/\" target=\"_blank\" rel=\"noreferrer noopener\">memory recall<\/a>.<\/p>\n\n\n\n<p>What is most intriguing is that this seems to be occurring when the brain is shutting down at the end of life. This study supports these descriptions and certainly raises the possibility that a marker of lucidity at the end of life may have been discovered,\u201d says Parnia.<\/p>\n\n\n\n<p>Still, the team who worked with the patient can\u2019t be certain that his life was flashing before his eyes because his health was already in decline at the time of&nbsp;<a href=\"https:\/\/www.popularmechanics.com\/science\/health\/a25633042\/autopsy-history\/\" target=\"_blank\" rel=\"noreferrer noopener\">death<\/a>\u2014he had suffered brain injuries that included bleeding, swelling, and seizures. Additionally, he had been taking anti-seizure drugs which further complicate what the data looked like as well as the interpretation of that data. Further, the team didn\u2019t have healthy scans of the patient\u2019s brain to compare against the more recent scans in which the patient was already in decline.<\/p>\n\n\n\n<p>In their paper, the team who worked with this patient theorized that because cross-coupling\u201d between the alpha and gamma waves indicates memory recall in healthy patients, this particular patient could have been experiencing a recall of life,\u201d or what is often referred to as someone\u2019s life flashing before their eyes. Alpha brain waves are produced when we\u2019re alert but calm and help us with activities like learning and coordination. Gamma waves are the fastest and are associated with high-level alertness, cognition, memory, and focus.<\/p>\n\n\n\n<p>According to Parnia, while the brain is in the process of shutting down and dying, there is disinhibition of parts of the brain (i.e. emergence of functions) that are ordinarily depressed by our usual brain activity,\u201d such as those we use to get through our day-to-day tasks. Because of this, we\u2019re granted access to what Parnia refers to as aspects of reality at death that we would ordinarily not have access to,\u201d including the depths of our&nbsp;<a href=\"https:\/\/www.popularmechanics.com\/science\/a34496675\/consciousness-electromagnetic-theory\/\" target=\"_blank\" rel=\"noreferrer noopener\">consciousness<\/a>.<\/p>\n\n\n\n<p>To learn more about what happens within our brains during&nbsp;<a href=\"https:\/\/www.popularmechanics.com\/science\/a36712084\/can-science-cure-death-longevity\/\" target=\"_blank\" rel=\"noreferrer noopener\">death<\/a>&nbsp;is essentially impossible, though, because scientists would need to observe the neural activity of healthy subjects.<\/p>\n\n\n\n<p>We do not anticipate death in healthy subjects and therefore could not obtain recordings in the near-death phase in anything other than from circumstances involving pathological conditions in acute care hospital settings,\u201d the paper\u2019s authors note. That the team was able to capture the 87-year-old patient\u2019s brain waves as he died occurred entirely by happenstance, after all.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Daisy Hernandez Courtesy msn.com For the very first time, scientists have recorded the&nbsp;brain&nbsp;waves of a dying person.
