New Sensor Could Detect Real-Time Changes in Brain Serotonin Levels During Sleep, Fear
Written by AZoSensorsDec 24 2020
Serotonin is a neurochemical that plays a critical role in the way the brain controls our thoughts and feelings. For example, many antidepressants are designed to alter serotonin signals sent between neurons.

Preclinical experiments, primarily in mice, showed that the sensor could detect subtle, real-time changes in brain serotonin levels during sleep, fear, and social interactions, as well as test the effectiveness of new psychoactive drugs.

NIH STUDY: Researchers find evidence to suggest COVID-19 can cause brain damage

Three-year-old Colt Parris is doing much better after doctors believed he suffered a stroke after contracting COVID-19.
LOS ANGELES - According to a study from the National Institutes of Health, researchers found evidence to suggest that brain damage may be a product of COVID-19.
Researchers uncovered blood vessel damage and inflammation in the brains of 19 deceased COVID-19 patients. We found that the brains of patients who contract infection from SARS-CoV-2 may be susceptible to microvascular blood vessel damage. Our results suggest that this may be caused by the body’s inflammatory response to the virus said Avindra Nath, M.D., clinical director at the NIH’s National Institute of Neurological Disorders and Stroke (NINDS).

TORONTO Results from a study of 19 deceased COVID-19 patients in the U.S. suggests that those who contract a SARS-CoV-2 infection may be susceptible to brain damage. Scientists at the National Institute of Neurological Disorders and Stroke (NINDS) have conducted an in-depth examination of brain tissue samples from 19 coronavirus patients who had died between March and July 2020. After examining the brain tissue samples, scientists say they spotted brain damage caused by thinning and leaky brain blood vessels. The results were published in a letter to the New England Journal of Medicine. âWe found that the brains of patients who contract infection from SARS-CoV-2 may be susceptible to microvascular blood vessel damage. Our results suggest that this may be caused by the bodyâs inflammatory response to the virusâ Dr. Avindra Nath, clinical director at NINDS, said in a statement. âWe hope these results will help doctors understand the full spectrum of p
