A growing body of researchers is utilizing optical imaging to monitor activity in the brain. One type of optical imaging, two-photon calcium imaging, has been widely adopted for its ability to record ...

MIT engineers used voltage imaging to map single electrical spikes across nearly a whole zebrafish brain at 200 scans per ...

New ultra-fast sensors developed at Janelia can detect calcium ions nearly as fast as they are released from neurons, allowing scientists to tease out the individual, milliseconds-long signals passing ...

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 have developed a calcium sensor for use in magnetic resonance imaging (MRI) that they hope can one day track electrical activity in neurons deep in living brains. The tool potentially ...

Neuroscientists have developed an MRI sensor that lets them monitor neuron activity deep within the brain by tracking calcium ions. This type of sensing could allow researchers to link specific brain ...

This article presents a carefully described technique with some tips on successful imaging of calcium with Fura-2 AM in the ventral spinal motor neurons of the spinal cord. 1. Preparing Enriched ...

A new calcium indicator called Calcium Green FlAsH allows researchers to monitor rapid and localized calcium dynamics in the cell. Got calcium? It's not just for strong bones. Calcium is an important ...
