Princeton University researchers have developed enhanced versions of neuronal calcium receptors that give them an unparalleled look at how cells in the brain communicate. In a new study in Nature Communications, the researchers worked to improve the function of the existing green fluorescent protein/calmodulin protein (GCaMP) sensors, which researchers can inject into the bloodstream and let travel to the brain. When they are activated by calcium activity, they glow green. The Princeton scientists tweaked the GCaMP sensors in their latest work, to let them keep up with the rapid pace of neuronal activity. This will let scientists better study the many tangled networks of neural activity in the brain.
