The brain contains many cell types, from the prominent neurons to the lesser-known microglia. The latter are integral to the brain's immune system and play a crucial role as the brain's cleanup crew.

A stem cell therapy for stroke restored neuron function and revealed how transplanted cells navigate the nervous system.

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

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 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 ...

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 ...
