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 ...

When we learn a new motor skill—whether mastering a piano passage or refining balance while walking—the brain must reorganize the circuits that control movement. For decades, this process of synaptic ...

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 ...

“If we go back to the early 1900s, this is when the idea was first proposed that memories are physically stored in some location within the brain,” says Michael R. Williamson, a researcher at the ...

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 ...
