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 ...

Calcium ions are essential to signal transduction in virtually all cells, where they coordinate processes ranging from embryogenesis to neural function. Although optical probes for intracellular ...

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 ...

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 ...

Combining microscopy, scanning, and deep learning enables more precise imaging of functional dynamics in neural networks of human cortical organoids.

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 ...

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 ...
