For more than a century, the story of the brain has been told as a tale of neurons, with every thought and memory traced to their electrical chatter. That narrative is now being rewritten as evidence ...

What actually happens in the brain in cases of depression? Relatively unknown brain cells—"astrocytes"—are believed to play an important role. At the Uppsala Biomedical Center, lab researchers are ...

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 ...

New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest ...

An international research team has uncovered new insights into healthy brain aging. The researchers found that aging leads to ...

Researchers at Baylor College of Medicine have unraveled the processes that give astrocytes, the most abundant glial cell in the brain, their special bushy shape, which is fundamental for brain ...

Fatty diets and obesity affect the structure and function of astrocytes, the star-shaped brain cells located in the striatum, a brain region involved in the perception of pleasure generated by food ...

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 ...

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, ...
