CAMBRIDGE, MA -- When neurons fire an electrical impulse, they also experience a surge of calcium ions. By measuring those surges, researchers can indirectly monitor neuron activity, helping them to ...

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 ...

Molecular focus The GCaMP calcium indicator consists of a fluorescent protein attached to a calcium-binding protein called calmodulin, and a calmodulin-binding protein called M13 peptide. GCaMP ...
