The distribution of lowest tone-response thresholds was examined within 3 different isofrequency planes (10, 20 and 30 kHz) of the inferior colliculus (IC) of the house mouse. Lowest thresholds are located in, or slightly rostrolateral to the center of each isofrequency plane. Thresholds increase centrifugally, although in the rostrolateral direction the increase is less marked. The data show that, in addition to the dorsoventrally oriented tonotopical arrangement, there is a horizontal representation of thresholds within each isofrequency plane of the IC.
研究了家鼠下丘（IC）三个不同等频率平面（10、20和30千赫）内最低音调反应阈值的分布情况。最低阈值位于每个等频率平面的中心或略靠前外侧。阈值呈离心式增加，不过在前外侧方向增加不太明显。数据表明，除了背腹向的音频拓扑排列外，IC的每个等频率平面内还存在阈值的水平表征。
