Auditory evoked brain-stem responses were recorded using binaural stimulation on 12 test subjects. Rotation of the sound source in the horizontal plane was simulated digitally using a binaural mixing console. Binaural processing in the inferior colliculus was thus demonstrated in humans. The amplitude of the inferior colliculus response depends in an almost linear manner on sound direction and presents a typical directionality. While the amplitude is considered an important central code of sound direction, response latency of the inferior colliculus is controversial. The results confirm neuronal mechanisms which had been established by animal experiments for single units of the inferior colliculus and the auditory cortex.
对12名受试对象使用双耳刺激记录听觉诱发脑干反应。使用双耳混音控制台在水平面上对声源旋转进行数字模拟。由此在人类中证实了下丘的双耳处理功能。下丘反应的振幅几乎呈线性地取决于声音方向，并呈现出典型的方向性。虽然振幅被认为是声音方向的一个重要中枢编码，但下丘的反应潜伏期存在争议。这些结果证实了动物实验针对下丘和听觉皮层单个神经元所确立的神经元机制。
