Researchers think they've figured out why Einstein was such an Einstein. The team from Lausanne University has identified a previously unknown role for a type of brain cell of which Einstein was particularly well endowed, the glial cells.
The glial cells were thought to just hold neurons together but now they seem to be instrumental in brain activity by transmitting messages around the brain.
About 20-years ago UC Berkley scientists ran a comparison between a sample of Einstein's brain and the brains of some deceased (I hope) doctors. The only difference found was that Einstein had a lot more glial cells.
