Brain functions stem from and rely on electrical signals created and propagated by neurons. As such, scientists measure electrical signals to study neuronal function at both single-cell and systemic ...

A new study from Bar-Ilan University shows that one of sleep's core functions originated hundreds of millions of years ago in ...

A clearance mechanism involving microglia has been known to relieve neurons of toxic protein aggregates such as those associated with Alzheimer’s disease and Parkinson’s disease. Unfortunately, this ...

A team of researchers from the University of Massachusetts Amherst is the first to show how proteins called "chaperones" are vital in ensuring that neurons can transmit signals to one another. When ...

When triggered by an odor, rapid changes in membrane voltage and intracellular calcium ion levels occur in nematode olfactory neurons, causing membrane voltage sensors and calcium ion sensors to ...

Exercise, therefore, is potentially able to improve the brain's capacity to respond to insulin for neuronal function, he said ...

In many ways, the brain is uncharted territory akin to the deepest parts of the ocean and farthest reaches of outer space. As with any new frontier, navigating it requires a map. Researchers have ...

Fluctuations in brain activity, also known as neural variability, enable us to be flexible in adjusting our behavior to the current situation. A new study shows that neural variability increases ...

Neurodiversity advocates have long argued that autistic brains are differently wired. Now, new evidence shows they are right. Researchers have found atypical numbers of brain cells in two key areas of ...
