Written by Jenny Straiton

How past experiences interact with sensory input to infer speed and allow eye tracking moving objects. As a plane flies across the sky, the muscles that allow the eye to track its movement can set pace not only on the speed observed but also the speed they would expect from seeing planes before. New research from Duke University (NC, USA), published in Nature Neuroscience, has discovered the underlying circuit for this behavior and how the brain uses statistical inference about motion; showing how visual, sensory information works with prior experiences to predict and alter motor control and eye tracking movements....
