# How the brain tracks a tennis ball in a fraction of a second The neuroscience behind Wimbledon's 148 mph serves explained - **Source:** [Scientific American Content: Global](https://brifing.si/source/4f066134-e06d-4415-87ef-305e3dc2aba6) - **Published:** 2026-07-11 - **Topic:** [Career Growth](https://brifing.si/c/growth) - **Original article:** - **On Brifing:** https://brifing.si/s/cc82e24e-7730-4d87-a4ef-e19fc502220d ## The science behind fast serves The 148 mph serves at Wimbledon 2026 showcase the human brain's incredible predictive abilities. Tennis players don't track the ball in real-time but use neural anticipation mechanisms to predict opponents' moves before they happen. ## Delayed visual processing During the time it takes for visual information about a tennis ball to reach the brain, the ball travels several meters on court. The brain compensates by constantly making predictions about the ball's future position. ## Biomechanical cues Professional tennis players predict serves by reading subtle body movements, racket angles, and ball toss height. Thousands of hours of training refine their ability to interpret these minute cues. ## The brain's prediction engine: cerebellum The cerebellum, located at the brain's base, plays a crucial role in anticipatory movements. It creates internal models to calculate the ball's future position and sends precise commands to muscles. ## Visual cortex's contribution A specialized area called MT/V5 in the visual cortex calculates the ball's speed and direction within milliseconds. This information helps players perfect their positioning and timing. ## Neuroscience in sports performance Understanding brain functions in fast-paced sports like tennis reveals mechanisms behind quick decision-making in daily life. This knowledge shapes training methodologies and cognitive development strategies. ## Sources covering this story - https://www.scientificamerican.com/article/wimbledon-2026-opened-with-a-148-mph-serve-heres-how-tennis-players-brains-track-such-fast-balls/ — --- _Summary written by Brifing from the original reporting.
