Learning how to tie a shoe or shoot a basketball isn't easy, but the brain somehow integrates sensory signals that are critical to coordinating movements so you can get it right. Now, scientists have discovered that sensory signals in the brain's cerebral cortex, which plays a key role in controlling movement and other functions, have a different pattern of connections between nerve cells and different effects on behavior than motor signals. The motor area of the cortex sends signals to stimulate muscles.
