The optic tectum of the barn owl (Tyto alba) contains a neural map of auditory space consisting of neurons that are sharply tuned for sound source location and organized precisely according to their spatial tuning. The importance of vision for the development of this auditory map was investigated by comparing space maps measured in normal owls with those measured in owls raised with both eyelids sutured closed. The results demonstrate that owls raised without sight, but with normal hearing, develop auditory space maps with degraded precision and with aspects of topography that are abnormal.
仓鸮（Tyto alba）的视顶盖包含一个听觉空间神经图谱，该图谱由对声源位置具有敏锐调谐能力且根据其空间调谐精确组织的神经元组成。通过比较正常仓鸮与双眼睑缝合饲养的仓鸮所测量的空间图谱，研究了视觉对这种听觉图谱发育的重要性。结果表明，在没有视觉但听力正常的情况下饲养的仓鸮，其听觉空间图谱的精度会降低，且地形方面会出现异常。
