A research team has identified different subtypes of white matter (WM) astrocytes, including a unique type with the ability to multiply and potentially aid in brain repair. Using single-cell RNA ...

Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte, and for a long time, scientists thought its job was caretaking the brain, ...

As a neuromodulator, norepinephrine is a powerful force in the brain. We all know it orchestrates rapid changes in behavior such as the fight-or-flight response. Fewer people know that astrocytes ...

New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest that neuron-only brain models, such as connectomes, leave out a crucial ...

Astrocytes are highly heterogeneous neuroglial cells with distinct functional and morphological characteristics in different parts of the brain. They are responsible for maintaining a number of ...

Astrocytes — named for their star-like shape — are a type of brain cell as abundant as neurons in the central nervous system, but little is known about their role in brain health and disease. Many ...
