A neural circuit for controlling auditory granule cell activity

The dorsal cochlear nucleus (DCN) is the earliest site in the auditory system at which multisensory integration takes place. Multisensory inputs do not synapse directly onto the principal cells of the DCN but rather synapse onto an extensive network of interneurons composed of granule, unipolar brush, and Golgi cells. This network is thought to process multisensory signals before ultimately sending some filtered version of the signal to DCN principal cells.
