The motor cortex does not represent a continuous map of the body.
How does our brain control everyday behaviours, such as grasping a cup of coffee or telling a joke? A century of experimental neurology testifies that a thin strip of motor cortex running sideways down the outer surface of the brain translates voluntary actions into muscle movements.
This strip is usually thought of as representing a continuous map of the human body, with separate sections each containing neurons that contact the spinal cord to operate a particular group of muscles. ‘Higher’ regions of the brain act as puppeteers, orchestrating movements by creating appropriate spatio-temporal sequences of neuronal activity in the motor-cortex map.
