Brain Prediction Lets Pros Return 148mph Serves at Wimbledon

Summary
A 148mph Wimbledon serve can still be returned because elite players predict its path before their brains fully process the ball’s flight.
Around 0.1 second of visual-processing delay means the ball has already traveled several meters, so returners rely on cues from the toss, trunk rotation, arm motion and racket angle.
The cerebellum acts as a prediction engine, while motion-sensitive visual areas, parietal regions and motor cortex rapidly update where the ball will be and prepare the swing.
That anticipatory system explains why the fastest returns are not pure reflexes and may also aid rehabilitation, movement-disorder research and robots built for unpredictable environments.
