Here is an important reason to stay in touch with friends and family: social isolation causes memory and learning deficits and other behavioral changes. Many brain studies have focused on the effects ...

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 ...

Delivering a connection-building protein to star-shaped cells in the brain could reverse changes to neural circuits seen in ...

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 ...

Astrocytes, the supporting cells of the brain, could play a significant role in the pathogenesis of Alzheimer's disease (AD), according to a new study from the University of Eastern Finland. This is ...

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, ...

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 ...

Obesity is a global health problem, and research has shown that diets that are high in fats and sugars are a major contributor to this problem. Scientists have now shown that brain cells called ...

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 ...
