Brain Art

The latest issue of American Scientist features some beautiful artwork of the brain. They highlighted microetchings - "handmade lithographs that manipulate light on a microscopic scale to control reflectivity of metallic surfaces". One of the challenges of representing the brain in a 2D medium is that the neurons are so densely packed that it makes it difficult to appreciate the layers in a 2D way. Microetchings get around that by having different layers reflect light in different ways. Check out the video on microetchings here:
