In the brain, synaptic plasticity - the ability to change neuronal connections over time - is fundamental to learning and memory. Traditionally, science has focused on nerve cells and their synapses.

Add Yahoo as a preferred source to see more of our stories on Google. A new MIT study suggests astrocytes, once seen as support cells, may play a central role in memory storage and brain capacity.

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 ...

Increased expression of the Ang‐II (Angiotensin II) precursor AGT in aged astrocytes lead to increased Ang‐II signaling from aged astrocytes to endothelium, thus increasingblood–brain barrier (BBB) ...

Your brain’s “stop eating” signal may come from an unexpected source. Researchers found that astrocytes—once thought to just support neurons—actually play a key role in controlling appetite. After a ...

When the stomach is full, how does the brain know to stop eating? Scientists long assumed the answer lies mainly with neurons ...

The human brain holds a staggering number of connections, yet scientists have long struggled to explain how it stores so much information. A new study from MIT researchers suggests the answer may lie ...
