Researchers say unlocking the higher frequencies via therapies could help to restore quality sleep in those with PTSD.<\/p>\n<p>Source: Virginia Tech.<\/p>\n<p>During periods of rapid eye movement (REM) sleep, brain activity often resembles that of awake behavior. At times, the brain can actually be more active during REM sleep than when you\u2019re awake. It\u2019s why REM sleep is sometimes called \u201cparadoxical sleep,\u201d said Virginia Tech neuroscientist Sujith Vijayan.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Summary: In people with PTSD, during REM sleep norepinephrine and serotonin levels remain high, reducing the brain\u2019s ability to inhibit fear-expression neurons through neural rhythms sent between the prefrontal cortex and amygdala.
