Schematic outline of auditory brainstem nuclei. Sound information is transduced in the hair cells of the cochlea and conveyed to the central auditory processing centers. The LSO is central for processing interaural level differences to detect sound sources in the horizontal plane in high frequency hearing animals. It receives excitatory input via the ipsilateral aVCN and inhibitory input via the MNTB, which in turn gets excitatory input from the contralateral aVCN. In addition, the MSO and the SPN receive inhibitory input via the MNTB. Note that not all inhibitory inputs are depicted. Gray: tonotopic gradient; green: VIAAT-immunoreactivity; blue: excitatory connection, red: inhibitory connection. aVCN: anteroventral cochlear nucleus; LNTB: lateral nucleus of the trapezoid body; LSO: lateral superior olive; MNTB: medial nucleus of the trapezoid body; MSO: medial superior olive; SPN: superior paraolivary nucleus, VNTB: ventral nucleus of the trapezoid body
