An important function of the auditory system is to identify the direction of a sound source. For this purpose the auditory system computes auditory localization cues, like small time differences in the arrival of the sound to one ear versus the other or differences in the intensity of the sound between the two ears. The translation of these cues to actual locations in space is learned through experience early in life. We study experience-dependent learning of auditory space in the barn owl, a species with a highly developed sound localization system. It was found that experience dependent learning in the barn owl is guided, in part, by information coming from the visual system. In this seminar I shall reflect on where and how in the brain visual signals interact with auditory signals to guide plasticity and present recent results suggesting that visual signals can instruct changes in auditory tuning.
