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 ...

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 ...

Clusters of proteins found on neurons are calcium-signaling “hotspots” that link electrical signals to gene expression, allowing neurons to produce crucial proteins. The discovery may potentially lead ...

Researchers have built a tiny, lightweight microscope that captures neuron activity with unprecedented speed that can be used in freely moving animals. The new tool could give scientists a more ...

CAMBRIDGE, MA -- Using a fluorescent probe that lights up when brain cells are electrically active, MIT and Boston University researchers have shown that they can image the activity of many neurons at ...

Biomedical researchers at the University of California have built a camera that can image the brain of an alert mouse up to 3,000 frames per second. This let them record for the first time the passage ...

Researchers at MIT have developed a calcium indicator, or sensor, that can overcome one of the main problems associated with a technique that is used to visualize, or map the activity of individual ...

Researchers at MIT and Boston University have teamed up to achieve the longstanding goal of imaging membrane voltage across a population of individual neurons in an awake, behaving mammal. Using a ...

Researchers have discovered how an ion channel in the brain's neurons has a kind of 'molecular memory', which contributes to the formation and preservation of lifelong memories. The researchers have ...
