Contralateral clicks normally activate units in the inferior colliculus of rats. Ipsilateral clicks usually inhibit this activity when their intensity just exceeds the contralateral intensity. When the contralateral dorsal and intermediate acoustic striae are lesioned as they pass over the restiform body, ipsilateral clicks inhibit even if they are substantially less intense than contralateral clicks. Contralateral click thresholds for unit activation are elevated by about 10 dB, but this shift in sensitivity cannot account for the marked advantage gained by the ipsilateral inhibitory input. These findings suggest that one or both of these pathways contributes heavily to binaural interaction at the inferior colliculus.
对侧滴答声通常会激活大鼠下丘中的神经元。当同侧滴答声的强度刚超过对侧滴答声时，通常会抑制这种活动。当对侧背侧和中间听纹在越过绳状体时受损，即使同侧滴答声的强度远低于对侧滴答声，也会产生抑制作用。激活神经元的对侧滴答声阈值提高了约10分贝，但这种敏感性的变化并不能解释同侧抑制性输入所带来的显著优势。这些发现表明，这些通路中的一条或两条在很大程度上促成了下丘的双耳相互作用。
