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 ...

A new Yale study has revealed that neurons — the energy-hungry cells that connect and direct activity in the brain — are equipped with “backup batteries” that kick in to keep the brain running during ...

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 ...

Scientists have shown that specialized cells involved in how the body responds to insulin are activated in the brain after exercise, suggesting that physical activity may directly improve brain ...
