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

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 ...

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.

Scientists at the University of Arizona, together with researchers from the US National Institutes of Health (NIH), have ...

A new model of memory — and a little-heralded type of brain cell — might explain why the human brain has such a huge storage capacity, researchers reported in the journal PNAS in May. The study looks ...

In both experiments, tweaks to the astrocyte clocks reliably slowed the mouse's sense of time. "We had no idea they would be that influential," Tso said. The scientists are already planning follow-up ...

A study published in Nature by researchers at Baylor College of Medicine changes the way we understand memory. Until now, memories have been explained by the activity of brain cells called neurons ...

Why are we able to recall only some of our past experiences? A new study led by Jun Nagai at the RIKEN Center for Brain Science in Japan has an answer. Surprisingly, it turns out that the brain cells ...

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 ...
