OCaMP: A New Calcium Indicator for Neural Imaging

This post was written by Abhi Aggarwal, from University of Calgary. Over the past few decades, genetically encoded calcium indicators (GECIs) have become a vital tool in neuroscience research. These fluorescent proteins light up in response to calcium, which is more than just the stuff that makes bones strong; it plays critical roles in nerve and muscle function, hormone release, and cell signaling throughout the body. Because calcium levels change rapidly during neuronal activity, scientists...
