Inside the Brain: An Entire Head in Cross-Section

The human brain appears to be incredibly psychedelic in brain scans. This video was created from images produced by the visible human project. A human head was frozen in a block of ice, sectioned with a macrotome, and photographed. 700 horizontal (or transverse) sections were produced, each with a thickness of 174 microns, and imaged at a resolution of 125um/pixel. The images have been interpolated by a factor of four. The animation starts near the top of the head and proceeds down towards the neck. The head faces towards the right hand side of the screen.
