Our brains are nearly three times the size of our earliest ancestors’, and it took just 3 million years to super-size them — a short timespan evolutionarily speaking. But does size really matter? Maybe not. Rather than bulk, the key to our intellectual prowess could be hidden in the way our neural connections are wired.
In this special issue of Discover, we explore the ways scientists are mapping our brains’ circuitry. Peering into the brain’s wiring has already led to a radical new treatment for depression, which we will explore in this issue. We’ll meet the scientists who are building maps that reveal the landscape of our grey matter in unprecedented detail.
Also in this issue, we take a trip to Harvard’s brain bank where thousands of specimens are waiting to be studied, and we take on a burning question of human evolution: If our brains our shrinking, are we more efficient, or just not as bright?
