This video shows a mouse brain thinking. Your brain is made up of 100 billion cells called neurons. Neurons send messages to each other – here, neurons glow green when they are sending messages.

Normally, brain cells don’t light up when they communicate. In this video, they contain special proteins engineered to glow when messages are fired off. Using high powered lasers and a trick of quantum physics, researchers can see the cells glow through layers of brain. 

These researchers study the hippocampus – the part of the brain that helps us navigate. In this video, we’re watching a mouse’s hippocampus as it runs a virtual-reality maze. This research helps us understand how our brains navigate and form memories.
