Corticospinal excitability during timed interception depends on the speed of the moving target

When intercepting a moving object, like catching a ball, we need to continuously combine visual motion signals to predict the object’s future location and enable accurate movement. Here, we show that preparatory suppression and facilitation of corticospinal excitability depend on the speed, but not the distance, of the moving target. These findings reveal that differences in interception timing are closely linked to changes in motor system excitability.
