Treasures hidden on Canadian campuses: From Einstein’s brain to a -273C fridge

They all soak in diluted formaldehyde in an oversized fridge at McMaster’s school of medicine, but one of the 125 brain slides in McMaster’s collection is extra-special: It’s a preserved slice of Albert Einstein. For three decades, Sandra F. Witelson has been weighing and measuring grey matter to explore the relationship between brain structure and cognitive function. Einstein’s reasoning-responsible parietal lobe, as it turns out, proved 15 per cent larger than average.
