Exploring how astrocytes respond to spinal cord injury or stroke-induced tissue damage
Past neuroscience studies found that when the central nervous system (CNS) is damaged, for instance following a stroke or spinal cord injuries, the lesions become surrounded by borders of newly proliferated astrocytes.
Forecasting method may help people with epilepsy predict their seizures
A team of epilepsy specialists at UC San Francisco has developed a method to predict 24-hour seizure risk. The discovery, which may be scalable to large numbers of patients, could help to improve the quality of life for the ...

Computational neuroscientists show how astrocytes increase flexible learning
Star-shaped glial cells, so-called astrocytes, are more than just a supporting cell of the brain. They are actively involved in learning processes and interact with nerve cells. But what exactly is it that astrocytes do?

Late bedtimes and not enough sleep can harm developing brains—and poorer kids are more at risk, say neuroscientists
Shorter sleep and later bedtimes are linked to potentially harmful functional changes to parts of the brain important for coping with stress and controlling negative emotions, our recently published research found. And children ...

Researchers use MRI scans and karaoke to better understand the nature of blushing
A small team of psychologists and neurologists from the University of Amsterdam, in the Netherlands, and D'Annunzio University of Chieti–Pescara, in Italy, has found that blushing may be more related to an increase in emotional ...
How our brains learn new athletic skills fast: Investigating electrocortical activity and faster locomotor adaptation
You join a swing dance class, and at first you're all left feet. But—slowly, eyes glued to the teacher—you pick up a step or two and start to feel the rhythm of the big band beat. A good start. Then you look over and ...
