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 ...

Research has shown that a good night's sleep has many benefits, including memory consolidation. How sleep enables the brain to strengthen memories is still not completely understood, but a new study ...

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 element sodium plays a key role in nervous system function. An international research team headed by the Institute of Neurobiology at Heinrich Heine University Düsseldorf (HHU) has now conducted a ...

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 ...

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, ...

The adult brain may be far better at repairing itself than scientists once believed. In mice, researchers discovered a special group of support cells called astrocytes that respond to damaged brain ...

Epilepsy, where patients suffer from unexpected seizures, affects roughly 1% of the population. These seizures often involve repetitive and excessive neuronal firing, with the trigger behind this ...

Recent work has revealed some of the many crucial functions of astrocytes, brain cells that were once thought to play primarily supportive roles for neurons. Astrocytes do handle debris around neurons ...
