CLARITY allows molecular analysis of the intact brain. Each
color represents a different molecular label; this labeling can happen after
the brain is clarified but still fully intact. This image shows the
hippocampus, a structure important for many important roles including learning,
memory, and emotion.
For scientists working to uncover the mysteries of the
brain, fat is a problem. The fats inside cells bend and scatter light,
obscuring researchers’ views when they try to peer deep into tissue.
