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 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 ...

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 ...

Closely related dopamine-releasing neurons in the olfactory bulb behave in fundamentally different ways depending on their physical structure.

A research group at the Massachusetts Institute of Technology (MIT) in the United States has announced that it has developed a flexible thin-film material that can change shape when exposed to light ...

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.

Wearable devices like smartwatches and fitness trackers interact with parts of our bodies to measure and learn from internal processes, such as our heart rate or sleep stages. Now, MIT researchers ...
