To better model how neurons fire and interact with glia, some scientists place the cells into a brain or grow them in an organoid. Others have produced little spheres of human neural tissue by ...

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 ...

Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte ...

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 ...

Astrocytes use the MEGF10 receptor to prune synapses in the striatum, a process essential for dopamine-driven motor learning.

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 ...

Cells feature an array of biological cascades to respond to stressors such as protein aggregates, viruses, and DNA damage. When these pathways are activated too much or for too long, things can go ...
