MIT neuroscientist and professor Nancy Kanwisher is really committed to teaching students about the brain. So committed, in fact, that she shaved her head and enlisted grad student Rosa Lafer-Souza to draw on her skull in order to make it easier to visualize the different parts of the brain and where specific regions of the cortex—the pizza-sized outer portion of the brain that controls most of our actions—are located.

She shows viewers the specific regions responsible for recognizing faces, seeing scenes, and the TPJ (temporoparietal junction) which only engages when you think about what other people are thinking.
