The website is from the Institute for Anatomy at the University of Vienna and intends to help people understand human brain anatomy.
Plastination preserves the body in a state where a remarkable amount of detail can be seen.
You can navigate through the brain slice by slice, or see particular parts taken out and examined in detail.
Each part is also labelled, so if you’re keen to polish up your neuroanatomy, there’s plenty of material to help you on your way.
