Motor Prediction — The Brain’s Internal Simulator
The brain predicts the consequences of movement before the movement happens. This allows actions to feel smooth, controlled, and automatic.
The cerebellum builds “forward models” that simulate the expected outcome of a movement. When reality matches prediction, movement feels effortless. When prediction fails, movements feel clumsy or inaccurate.
