This new brain map shows almost 100 areas never described before

You don’t have to be a neurosurgeon to know it’s hard to get to the right place without a good map. But neuroscientists have been blundering around with blurry brain maps, which sometimes aren’t very detailed, or omit important functions. That’s why a new map is so exciting — it shows nearly 100 areas that hadn’t been reported before.

The map, described in a study published today in Nature, is a detailed look at the part of the brain that handles all your senses, as well as your motion — plus some other functions like problem solving and emotional regulation. It’s called the cerebral cortex, and it’s the brain’s outer layer of nerve tissue. Think of it as "a sheet about the size of a large pizza, and about the thickness of the cardboard...
