Scientists have developed a new technique to study the brain, by making it transparent.
Using a post-mortem mouse brain, the researchers were able to use a water-based gel to prop up the structure of the brain, then remove the lipids.
Lipids are a fatty tissue that prevent chemicals and light permeating the brain, but also help it hold its structure.
This technique makes it possible to study the intact (as opposed to sectioned) brain.
