用钨微电极分离麻醉猫的上级-橄榄复合体中的单个单位，并观察它们对音调和咔哒声的反应。这个复杂的核聚集体之一，即内侧上级橄榄核，包含单位，是敏感的双耳提出点击。传递到一只耳朵的咔嗒声产生的反应可能被传递到另一只耳朵的咔嗒声抑制。这种抑制对于双耳呈现的短声之间的时间差小至8微秒是有效的。这个核的许多单位表现出自发活动，并可能被音调驱动。虽然当一个音调传递到一只耳朵时会使一个单位兴奋，但同样的音调传递到另一只耳朵时会抑制它。从上级-橄榄复合体的其他核团中分离和研究的单位，例如，斜方核和外侧上级橄榄核仅显示单耳反应。最后，由点击刺激引起的慢波反应的配置在不同的核团中变化很大。
Single units in the superior‐olivary complex of anesthetized cats were isolated with tungsten microelectrodes, and their responses to tones and clicks observed. One of the nuclear aggregates of this complex—namely, the medial superior olivary nucleus—contains units that are sensitive to binaurally presented clicks. A click delivered to one ear produces a response which may be inhibited by a click to the opposite ear. This inhibition is effective for time differences between the binaurally presented clicks of as little as 8 μsec. Many units of this nucleus exhibit spontaneous activity and may be driven by tones. Although a tone excites a unit when it is delivered to one ear, the same tone to the opposite ear inhibits it. Units isolated and studied from other nuclei of the superior‐olivary complex, e.g., trapezoid nucleus and lateral superior‐olivary nucleus show only monaural responses. Finally, the configuration of the slow‐wave response evoked by a click stimulus varies considerably in the various nuclei...
