GCaMP

GCaMP is a specialized protein used by scientists to monitor brain activity. It works like a biological light switch: when neurons (brain cells) become active and receive signals, they cause calcium ions to flood into the cells. GCaMP detects these calcium changes and glows brighter or dimmer accordingly. By using imaging techniques, researchers can visualize and track neuronal activity in real-time, helping to understand how the brain processes information, learns, and responds to stimuli. GCaMP is a powerful tool for studying the nervous system with high spatial and temporal precision.
