There is a positive correlation between the amount of motor cortex devoted to the control of a particular movement and the degree of precision required by the movement. This means that the more precise a movement needs to be, the more of the motor cortex will be allocated to control it. This is supported by research showing that movements requiring fine motor control, such as those involved in playing a musical instrument, require larger areas of the motor cortex to be activated than movements requiring less precision, such as walking.
