Is your brain simply a command center, receiving information and sending orders? Try catching a ball. Seeing it is only the start: your brain has to predict where it will be when your hand gets there. Light from the ball, plus signals from your eyes and body, becomes messages carried through networks of neurons. Your brain combines those signals with past experience, then chooses movements to put your hand in the right place. But here's the turn: it isn't just reacting. It is constantly predicting what will happen, acting on that prediction, and correcting it. If the ball arrives sooner than expected, that mismatch changes what your brain expects next time. Learning means those networks adjust. It's a simple model, not the whole brain, but the loop is clear: sense, predict, act, update. So no: it turns signals into predictions, choices, and actions, then rewires itself from the result.
