When a person frequently practices a movement, the area of the motor cortex devoted to that movement will?

The correct answer is that the area of the motor cortex devoted to a frequently practiced movement will enlarge. This process is known as cortical plasticity or neuroplasticity, which is the brain's ability to reorganize itself by forming new neural connections.

When a movement is practiced repeatedly, the connections between neurons responsible for that movement become stronger and more efficient. As a result, the brain allocates a larger area of the motor cortex to control that specific movement. This is especially evident in athletes or musicians who develop specific motor skills through consistent practice. Enhanced representation in the motor cortex leads to improved coordination, precision, and efficiency of the movement.

Understanding this concept emphasizes the importance of practice and skill acquisition in motor learning, as the brain's structural changes can significantly enhance performance in various physical activities.
