New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest ...

Why do we sometimes keep eating even when we're full and other times turn down food completely? Why do we crave salty things ...

Amyloids are typically associated with neurodegenerative diseases such as Alzheimer's, Huntington's and Parkinsons. They form tightly packed, highly stable "detrimental" protein fibers that destroy ...

Researchers found that cutting the vagus nerve in mice reduced dopamine activity and lessened the frequency of reward ...

Some older male rats prefer familiarity over new social situations. Manipulating how their neurons communicate with a ...

Parkinson's disease (PD) is the second most common neurodegenerative disease after Alzheimer's disease, affecting more than ...

Using an aging clock, researchers from the University of Cologne have used the Caenorhabditis elegans model organism to demonstrate that nerve cells age differently. They identified both the causes of ...

Scientists rebuilt human brain circuits in the lab and discovered that the thalamus acts as a central organizer of cortical wiring. The findings offer new insight into how brain networks form and why ...

When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer’s-like ...

Rather than use AI to achieve scientific breakthroughs, Anthropic is betting AI agents can make the routine work of science more efficient.

Researchers have developed a way to grow a highly specialized subset of brain nerve cells that are involved in motor neuron disease and damaged in spinal injuries. Their study, published today in ...

Tech advances already show a future of testing in which we might not have to suffer and die while waiting for systems that ...
