Adaptive Response Behavior in the Pursuit of Unpredictably Moving Sounds.

Although moving sound-sources abound in natural auditory scenes, it is not clear how the human brain processes auditory motion. Previous studies have indicated that, although ocular localization responses to stationary sounds are quite accurate, ocular smooth pursuit of moving sounds is very poor. We here demonstrate that human subjects faithfully track a sound's unpredictable movements in the horizontal plane with smooth-pursuit responses of the head.
