NIH’s YouTube Channel, NIHOD, recently featured a data visualization of a magnetic resonance imaging (MRI) scan of the human brain video. An MRI is a medical imaging procedure used to help examine the inside of the human body. This eye-catching video shows greater detail of the hippocampus, a brain region that helps you create new memories. The data visualization helps researchers map out entire brain-wide circuits, and provides a new, cool way to look at the human brain.
