Calcium sensor leaves permanent mark in activated neurons

Neuroscience—and science in general—is constantly evolving, so older articles may contain information or theories that have been reevaluated since their original publication date. Researchers have engineered a fluorescent sensor that irreversibly switches from green to red when a neuron fires, thereby serving as a permanent mark of neuronal activation. They described the unpublished work Monday at
