According to researchers at Rutgers University, sleep deprivation can cause fear. The researchers found that using sleep-monitoring exercises and brain scans to keep sleep quality constant reduces activity in the brain regions that learn fear.
Experts recommend monitoring soldiers' sleep patterns before sending troops to lower the risk of post-traumatic stress disorder (PTSD) after the war, Daily Mail said. The goal is to track how fast the sleeping eye movements are to monitor and monitor the effect of the soldier's brain learning fear in the least active sleep phase.
The researchers measured twelve male and five female students sleeping at home and measuring 17 brain waves for a week of sleep monitoring. In the following week, students were trained to associate with flashing lights or neutral images under weak electrical stimuli, and then mapped responses to student images. In the third experiment, the students were connected to a poly- sonograph that gave accurate results.
After the experiment, the researchers said they could adjust the levels of norepinephrine, a neurotransmitter known as "anadrenaline" in the brain, by sending more time to the REM sleep phase. Neurotransmitters are related to how combat and flight responses are controlled for soldiers. Low levels of neurotransmitters generally lower the susceptibility to fearful stress stimuli, Medical News Today reported.
