There are three major projections from the cochlear nuclei.

Each of the three cochlear nuclei are tonotopically organised.

In this way, the cochlear nuclei inherit the tone based organization of the cochleae.

The cochlear nuclei have long been thought to receive input only from the ipsilateral ear.

The particular physiology and morphology of each cochlear nuclei cell type enhances different aspects of sound information.

The MSO contains cells that function in comparing inputs from the left and right cochlear nuclei.

The central projection of DiI and DiA traces fibers to the cochlear nuclei (Fig.

The lateral lemniscus is located where the cochlear nuclei and the pontine reticular formation (PRF) crossover.

In general, the cells of the cochlear nuclei tend to preserve or even enhance the timing information that is provided by each fiber of the cochlear nerve.

When the CS is a tone, auditory information is received via the cochlear nuclei (Steinmetz & Sengelaub, 1992).

Our data show that at least a cochleotopic projection in the cochlear nerve and the cochlear nuclei develops even in Brn 3c null mutants (Fig.

The SOC receives input from cochlear nuclei, primarily the ipsilateral and contralateral AVCN.

There are four types of principal cells found in the cochlear nuclei: Bushy cells, stellate cells, octopus cells, and fusiform cells.

The cochlear nuclei (CN) are two heterogeneous collections of neurons in the mammalian brainstem that receive input from the cochlear nerve, which carry sound information from the cochleae.

Four nuclei make up the SOC but only the medial superior olive (MSO) and the lateral superior olive (LSO) receive input from both cochlear nuclei.

The function of the lateral lemniscus is not known; however it has good temporal resolution compared to other cells higher than the cochlear nuclei and is sensitive to both timing and amplitude changes in sound.

This sound information, now re-encoded, travels down the vestibulocochlear nerve, through intermediate stations such as the cochlear nuclei and superior olivary complex of the brainstem and the inferior colliculus of the midbrain, being further processed at each waypoint.

The cochlear nerve spans from the cochlea of the inner ear to the ventral cochlear nuclei located in the pons of the brainstem, relaying auditory signals to the superior olivary complex where it is to be binaurally integrated.

Qualitative comparable central projections are found in wildtype control littermates (data not shown) and suggest that the central projection to cochlear nuclei is at least until P8 in mice not critically dependent on auditory information or other hair cell-mediated influences, in agreement with recent suggestions [ 5 19 ] .

The fibers of the auditory nerve innervate both cochlear nuclei in the brainstem, the cochlear nucleus magnocellularis (mammalian anteroventral cochlear nucleus) and the cochlear nucleus angularis (see figure; mammalian posteroventral and dorsal cochlear nuclei).

There are three major projections from the cochlear nuclei.

Each of the three cochlear nuclei are tonotopically organised.

From the cochlea, peripheral auditory information goes to the cochlear nucleus.

It consists of fibers arising from the ventral cochlear nucleus.

In this way, the cochlear nuclei inherit the tone based organization of the cochleae.

The cochlear nuclei have long been thought to receive input only from the ipsilateral ear.

It projects centrally to the brainstem, where its fibers synapse with the cell bodies of the cochlear nucleus.

The particular physiology and morphology of each cochlear nuclei cell type enhances different aspects of sound information.

All of these neurons synapse onto the cochlear nucleus, which is split into dorsal and ventral regions.

Late appearance and deprivation-sensitive growth of permanent dendrites in the avian cochlear nucleus (Nuc.

Large multipolar cells project to the cochlear nucleus, but not the IC, in both cat and guinea pig.

The cochlear nucleus is the first 'relay station' of the auditory nervous system and receives mainly ipsilateral afferent input.

The MSO contains cells that function in comparing inputs from the left and right cochlear nuclei.

The more elongated cells that project to the cochlear nucleus to not project to the ICC.

Granule cells in the dorsal cochlear nucleus play a role in the perception and response to sounds in our environment.

The fibres from the receiving station of the inner ear, the organ of Corti synapse first at the cochlear nucleus.

Auditory nerve fibers provide synaptic connections between the hair cells of the cochlea and the cochlear nucleus within the brainstem.

Next in the pathway is the cochlear nucleus, which receives mainly ipsilateral (that is, from the same side) afferent input.

They reflect neuronal activity in the auditory nerve, cochlear nucleus, superior olive, and inferior colliculus of the brainstem.

This original ABI consisted of two ball electrodes which were implanted near the surface of the cochlear nucleus.

The second set of inputs is relayed through a set of small cells called "granule" cells in the cochlear nucleus.

Bushy cells are found in the anterior ventral cochlear nucleus (AVCN).

The inferior colliculus receives input from both the ipsilateral and contralateral cochlear nucleus and respectively the corresponding ears.

Inhibitory inputs are received at the LSO from globular bushy cells of the contralateral cochlear nucleus.

Octopus cells are found in a small region of the posterior ventral cochlear nucleus (PVCN).
