cortex

The human brain is exquisitely tuned to identify faces and facial expressions, which are so important to human social interaction. Researchers have found that certain areas of the human cerebral cortex are specialized for processing visual information about faces.

On today's Moment of Science we're going to perform a little experiment in order to learn a little bit about the motor cortex--a strip of tissue running from ear to ear across the surface of the brain that is responsible for controlling voluntary movement.
