Virginia Tech&#8217;s neuroscientists recently discovered why this happens using brain models. <a href=\"https:\/\/vtx.vt.edu\/articles\/2023\/01\/science-sujith_vijayan_neroscience_ptsd_rem_sleep.html\" target=\"_blank\" rel=\"noopener\">reported<\/a>. These findings can be used to develop therapies that may reduce the impact of PTSD on sleep.<\/p>\n<p>The brain can be quite active during rapid-eye movement (REM) sleep. This is what Sujith Vijayan (Virginia Tech neuroscientist and professor, co-author of this study), called it. \u201cparadoxical sleep.\u201d The high activity of REM sleep combined with post-traumatic Stress Disorder can help people suffering from this disorder relive painful past memories. \u201cover and over\u201d Vijayan again.<\/p>\n<p>Normaly, the brain can summon up emotional memories during REM to purge the emotional charge. For people with PTSD, however, this normal process may malfunction and painful memories can be brought up night after night.<\/p>\n<p>Their study revealed that <a href=\"https:\/\/www.jneurosci.org\/content\/43\/3\/433\" target=\"_blank\" rel=\"noopener\">Published<\/a> Vijayan and his research team created a biophysical brain model that could be used to simulate neurophysiological functions such as communication between brain parts, neurotransmitters and brain waves.<\/p>\n<p>Adjusting the brain rhythms between <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC2907136\/#:~:text=The%20prefrontal%20cortex%20(PFC)%20intelligently,brain%20regions%20(BOX%201).\" target=\"_blank\" rel=\"noopener\">Prefrontal cortex<\/a> The <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK537102\/\" target=\"_blank\" rel=\"noopener\">Amygdala<\/a> in the model, researchers were able to link lower levels of the neurotransmitters norepinephrine and serotonin with the brain\u2019s ability to restrain fear and pain-based memories during REM sleep. The researchers also discovered that PTSD patients had higher levels of serotonin, norepinephrine, and other neurotransmitters during REM sleep. This caused painful memories to repeatedly come to mind.<\/p>\n<p>Studies have also shown that REM sleep can reduce negative memories&#8217; emotional impact. It is not yet the. \u201cwild west\u201d Vijayan explained how REM sleep works. \u201cREM sleep is a lot harder to get your hands around. There are really good models out there for how non-REM sleep might consolidate memories and what role it might play in learning and memory. But when we talk about REM, there are no real, good models on how that stuff is happening,\u201d He said.<\/p>\n<p>This model, created by Vijayan with his team, provides a lot of insight. The brain wave rhythms of the amygdala and prefrontal cortex were examined. It was found that the strongest communication in the brain occurred between four to eight hertz on a theta range. This in turn inhibits fear expression cells during sleeping.<\/p>\n<p>Researchers adjusted the models to increase the levels of serotonin and norepinephrine during REM. However, the model was ineffective at suppressing fear expression cells when it contained four to eight hertz of the theta brain rhythm. However, they found that ten hertz was effective in suppressing fear expression cells within the PTSD brain model.<\/p>\n<p>These findings may lead to the creation of therapies, which Vijayan refers to as covert auditory stimuli. \u201cThat means I\u2019m playing those sounds and you\u2019re not aware of it while you\u2019re sleeping,\u201d He said. \u201cThat could be useful for any sort of disorder where sleep is disrupted, not only in PTSD, but in traumatic brain injury or Parkinson\u2019s disease. The idea is that by inducing desired neural dynamics, we can engage the recuperative powers of sleep.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Many people who suffer from post-traumatic stress disorder often relive highly-charged fearful and emotional memories while they sleep, and neuroscientists from Virginia Tech have recently discovered what is behind this phenomenon using models of the brain, the news outlet for Virginia Tech reported.
