COVID-19 can spark a severe immune response in the central nervous system, affecting immune cells in the vascular system and brain.
Resting is no substitute for deep sleep when it comes to keeping up with the intensive performance demands of daily life.
A new method for analyzing brain oscillation data can detect short beta wave bursts in real-time within neural frequency bands of 20 Hertz. The method also shows how rats can increase the occurrences of these bursts.
The smell of roses while learning and during sleep helps increase memory and learning skills. The study reports a significant increase in learning success by 30% if a person is exposed to the smell of roses during both learning and sleep phases.
Polydactyly, a condition where one is born with an extra finger, has significant benefits when it comes to motor skill and control. fMRI neuroimaging reveals those with extra fingers are able to move the digits independently of other fingers. The findings could help with the development of new prosthetics that extend motor abilities.
Deep brain stimulation provides a significant reduction in the symptoms of depression for a number of patients with a treatment-resistant form of the disorder.
Researchers have successfully created a new map of the brain's immune system in both mice and humans. The findings suggest microglia all have the same core signatures, but can act differently, depending on their function. The map also details how the brain's immune system changes as multiple sclerosis progresses.
Studying animal models, researchers have identified previously unknown types of immune cells that are present in the brains of those with multiple sclerosis.
