视觉和听觉空间的神经地图在成人视顶盖中排列一致。在仓鸮，这种对齐的感觉地图被发现控制在个体发育过程中的视觉指令的听觉空间调谐的神经元。听觉空间调谐的大的适应性变化引起的提高猫头鹰与位移棱镜安装在眼镜架在眼前，神经元成为调整到声源位置对应的光学位移，而不是他们的正常，视觉感受野的位置。结果表明，在发展过程中的视觉经验校准顶盖听觉空间地图在特定地点的方式，规定其地形和对齐的视觉空间地图。
Neural maps of visual and auditory space are aligned in the adult optic tectum. In barn owls, this alignment of sensory maps was found to be controlled during ontogeny by visual instruction of the auditory spatial tuning of neurons. Large adaptive changes in auditory spatial tuning were induced by raising owls with displacing prisms mounted in spectacle frames in front of the eyes; neurons became tuned to sound source locations corresponding to their optically displaced, rather than their normal, visual receptive field locations. The results demonstrate that visual experience during development calibrates the tectal auditory space map in a site-specific manner, dictating its topography and alignment with the visual space map.
