The purpose of this study was to determine brain networks involved in motion perception of sounds. Ten healthy young volunteers measured their brain activity during a sound localization task and control tasks using functional MRI. An event-related design was used in this study. Stereo sounds moving in the 3D space were created by a personal computer, and presented binaurally through a pair of air conduct headphones during the sound localization task. And subjects were asked to judge the location and direction of the moving sounds. During the control task, non-moving sounds were used for stimuli. The intraparietal, premotor cortices of the bilateral hemisphere, and the cerebellar vermis were specifically activated during the sound localization task. These areas are believed to be involved in control of eye movements. Although, task-related eye movements were not observed in this study. Therefore, our results indicate that brain networks consist of these areas are related to motion perception of sounds, and that the fronto-parietal network may be a multi-modal network for spatial recognition.
