What the Maps in Our Brain Tell Us About the Learning Process

To fit all the billions of neurons in the human brain into our heads, they're organized so that brain regions are carefully mapped to things like vision and hearing. And understanding those maps can be a key to better understanding how the mind—and how learning—works, according to Rebecca Schwarzlose, a postdoctoral neuroscientist at Washington University in St. Louis, and author of the new book, "Brainscapes."
