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 ...

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 ...

In Nijmegen, Netherlands, researchers have installed the world's first microscope capable of live imaging of biological processes in such detail that moving protein complexes are visible. This new ...
