The cochlear nucleus (CN) or cochlear nuclear complex comprises two cranial nerve nuclei in the human brainstem, the ventral cochlear nucleus (VCN) and the dorsal cochlear nucleus (DCN). The ventral cochlear nucleus is unlayered whereas the dorsal cochlear nucleus is layered.

2021年6月12日 · The cochlear nuclei are a group of two small special sensory nuclei in the upper medulla for the cochlear nerve component of the vestibulocochlear nerve. They are part of the extensive cranial nerve nuclei within the brainstem.

The dorsal cochlear nucleus (DCN, also known as the "tuberculum acusticum") is a cortex-like structure on the dorso-lateral surface of the brainstem. Along with the ventral cochlear nucleus (VCN), it forms the cochlear nucleus (CN), where all auditory nerve fibers from the cochlea form their first synapses.

The cochlear nuclei are composed of a variety of neuronal types with distinctive patterns of dendritic branching. The cell types described in the human cochlear nuclei ( Moore and Osen, 1979 ; Adams, 1986 ) are generally, but not always, similar to those of other mammalian species.

2023年10月30日 · The cochlear nuclei comprise the dorsal (posterior) and ventral (anterior) group. Arising from the dorsal cochlear nucleus is the dorsal acoustic stria which traverses the midline, providing fibers to the contralateral lateral lemniscus which …

The cochlear nucleus comprises two physically distinct divisions: the dorsal cochlear nucleus (DCN) and the ventral cochlear nucleus. The ventral cochlear nucleus is further divided, on the basis of the pattern of termination of auditory nerve fibers, into the posteroventral cochlear nucleus (PVCN) and anteroventral cochlear nucleus (AVCN).

The cochlear nuclear complex comprises two nuclei, the ventral cochlear nucleus and the dorsal cochlear nucleus. The ventral cochlear nucleus is unlayered whereas the dorsal cochlear nucleus is layered.

Cochlear nuclei is the nuclei that receive first-order auditory input from the organ of Corti in the cochlea of the inner ear. The cochlear nuclei are divided into a dorsal and a ventral group.

The cochlear nuclear complex (CNC) is the first relay center in the auditory brain. From here the signals of the cochlear nerve diverges into a number of parallel ascending tracts, each with its own particular course and destination, as well as conduction velocities, properties and relays.

The cochlear nuclei, located bilaterally at the pontomedullary junction, are the first synaptic stations in the central auditory pathway. The cochlear nuclei are obligatory relays, meaning that all information flowing from the cochlea must here encounter at least one synapse before being transmitted to higher auditory centers.
