听觉和视觉空间映射在仓鸮的视觉顶盖上。通常情况下，这些空间地图是紧密相连的。在年轻的仓鸮身上单方面插入耳塞，破坏了构成听觉地图基础的双耳线索。然而，当对这些成年鸟的喙部进行录音时，听觉和视觉地图都已记录在案。当从这些成年鸟身上取下耳塞并恢复双耳平衡时，相对于视觉地图和构造区的物理边界，听觉地图发生了实质性的变化。这些结果表明，在视觉顶盖中产生空间听觉地图的神经连接可以通过经验进行修改，从而保持感觉模式之间的空间一致性。
Auditory and visual space are mapped in the optic tectum of the barn owl. Normally, these maps of space are in close mutual alignment. Ear plugs inserted unilaterally in young barn owls disrupted the binaural cues that constitute the basis of the auditory map. Yet when recordings were made from the tecta of these birds as adults, the auditory and visual maps were in register. When the ear plugs were removed from these adult birds and binaural balance was restored, the auditory maps were shifted substantially relative to the visual maps and relative to the physical borders of the tecta. These results demonstrate that the neural connectivity that gives rise to the auditory map of space in the optic tectum can be modified by experience in such a way that spatial alignment between sensory modalities is maintained.
