"Our motor control system is based on a rather fixed representation of the motor and sensory systems in the brain in a formant of maps that have body part coordinates," Hochner explains.
A system of coordinates in which a point is located by its distance and direction (Angle) from a fixed point on a reference line (called the polar axis).
