Scientists at the Albert Einstein College of Medicine at Yeshiva University have developed a breakthrough technique that has allowed them to 'film' the brain as it forms new memories. The incredible video shows fluorescent tagged molecules moving in real time as they form memories inside a mouse brain. The researchers think their 'mouse model' could have major implications for understanding of how the brain works. Check out the video here.
