单位活动的记录显示4-6毫秒的潜伏期响应点击刺激提供的证据表明，齿状核可以作为一个短潜伏期的听觉中继。在此基础上，再加上齿状核内注射菜豆白细胞凝集素的纤维填充物，提出了耳蜗背腹核、齿状核和头侧丘脑之间的一条新的听觉通路。该通路可以提供直接的，短潜伏期的传输到运动皮层，绕过经典的听觉接受皮层。
Recordings of unit activity showing 4-6 ms latency responses to a click stimulus provided evidence that the dentate nucleus could function as a short-latency auditory relay. On the basis of these findings, plus fiber fillings from injections of phaseolus leucoagglutinin into the dentate, a new auditory pathway between dorsal and ventral cochlear nuclei, dentate nucleus, and rostral thalamus is proposed. The pathway could provide direct, short-latency transmissions to the motor cortex that bypass the classical auditory receptive cortex.
