AS WE SEE IT
Orange, purple, turquoise, red – Markus Cremer is hoarding over 50 bottles of nail polish in his drawer. All this in the name of research, specifically: of brain research. Cremer and his colleagues at the Institute of Neurosciences and Medicine (INM-1) use it to bond glass plates with a wafer-thin brain cut between them. With the brain section fixed in this way, the structures of its nerve fibres can be made visible with the aid of light. “We’ve tried a lot. Nail polish is simply the best for gluing two plates together. It dries quickly, holds well, can be easily removed again – and it always comes handy with a brush for application,” says Cremer.
