Astrocytes are star-shaped glial cells with many functions which include providing nutrient support to neurons, helping repair damage to nervous system tissue, regulating connectivity of brain ...

The brain is often described as a dense forest of connections, and for years scientists have searched for ways to trim that ...

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 ...

Astrocytes are star shaped cells that make up around 35% of human brain cells. They were once thought of as cells that simply supported neurons in the central nervous system (CNS). But in recent years ...

New research from Oregon Health & Science University for the first time documents the presence of astrocytes in zebrafish, a milestone that will open new avenues of research into a star-shaped type of ...

Alzheimer's disease (AD) is a neurodegenerative disorder that leads to progressive memory loss and a decline in mental functions. Several past studies have linked this disease to the accumulation of ...

The potential effects of astrocyte dysfunction in neurodegenerative diseases are summarized in Figure 2. AD is characterized clinically by cognitive loss in two or more domains, including memory, ...

When astrocyte function is disrupted, neurons in the brain's motor cortex struggle to execute and refine motion, a new study in mice shows. From steering a car to swinging a tennis racket, we learn to ...

Researchers have uncovered novel aspects of astrocyte function in olfactory, or smell, perception revealing changes in their gene expression patterns that turn these brain cells into a hub of ...

Researchers at Baylor College of Medicine reveal that astrocytes, the most abundant cells in the brain, play a direct role in the regulation of neuronal circuits involved in learning and memory. The ...
