Smooth mover

To move your body smoothly, you have to move your muscles in the right order, and stop one movement before starting another. Scientists think that an area of your brain called the basal ganglia is crucial for the overall control of sequences of movements. Damage to different parts of this area, as occurs in Parkinson and Huntington diseases, causes difficulties in planning and performing movements.
