The ventral cochlear nucleus is divided into the anterior ventral (anteroventral) cochlear nucleus (AVCN) and the posterior ventral (posteroventral) cochlear nucleus (PVCN). In the VCN, auditory nerve fibers bifurcate, the ascending branch innervates the AVCN and the descending branch innervates the PVCN and then continue to the dorsal cochlear ...
The ventral cochlear nucleus is unlayered whereas the dorsal cochlear nucleus is layered. Auditory nerve fibers, fibers that travel through the auditory nerve (also known as the cochlear nerve or eighth cranial nerve) carry information from the inner ear, the cochlea, on the same side of the head, to the nerve root in the ventral cochlear ...
The cochlear nucleus is the first site of the neuronal processing of the newly converted "digital" data from the inner ear (see also binaural fusion). In mammals, this region is anatomically and physiologically split into two regions, the dorsal cochlear nucleus (DCN), and ventral cochlear nucleus (VCN). The VCN is further divided by the nerve ...
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.
Math1/Math5 and FGF are two regulators essential for appropriate growth and development of the cochlear nucleus complex, which comprises both the ventral cochlear nucleus (VCN) and the dorsal cochlear nucleus (DCN). Sufficient FGF levels ensure proper morphology of the cochlear nuclei, while Math5 insures correct size and processing of the ...
The trapezoid body or ventral acoustic stria is a structure in the pontine tegmentum formed by the crossing-over (decussation) of a portion of the efferent second-order fibers of the ventral cochlear nucleus (anterior cochlear nucleus).
The cochlear nucleus is the first 'relay station' of the central auditory system and receives mainly ipsilateral afferent input. The three major components of the cochlear nuclear complex are (see figure below): the dorsal cochlear nucleus (DCN) the anteroventral cochlear nucleus (AVCN) the posteroventral cochlear nucleus (PVCN)
Bushy cells are two types of second order neuron found in the anterior part of the ventral cochlear nucleus, the AVCN. They can be globular or spherical giving outputs to different parts of the superior olivary complex.
