在猫头鹰（Tyto alba）中脑听觉核的外侧和前部发现了仅当声音起源于有限的空间区域时才对声音作出反应的听觉单位。这些单位所反应的空间区域（它们的感受野）在很大程度上与声音刺激的性质和强度无关。这些单位根据其感受野的相对位置在中脑听觉核团内系统地排列，从而创建听觉空间的生理地图。
Auditory units that responded to sound only when it originated from a limited area of space were found in the lateral and anterior portions of the midbrain auditory nucleus of the owl (Tyto alba). The areas of space to which these units responded (their receptive fields) were largely independent of the nature and intensity of the sound stimulus. The units were arranged systematically within the midbrain auditory nucleus according to the relative locations of their receptive fields, thus creating a physiological map of auditory space.
