You'll have to forgive the morbid short comedy The Grey Matter a few dozen puns, but it makes up for it by being deliciously macabre.

Archaeologists in Norway have found an 8,000 year-old skull at a Stone Age site that could very well be of human origin. Remarkably, it contains a grey, clay-like substance thought to be the preserved remains of the brain. If confirmed, it could be one of the oldest human brains ever found.
Scientists have created the first map of the ways that the white matter in our brains connects with itself, and with our grey matter. The takeaway? It works like a scaffold, researchers say — and some connections are much more important than others.
Grey matter is fundamental to our minds - indeed, it's so important that the term is often used to refer the brain as a whole. But it turns out that white matter may be where our thinking happens.
