  • Auditory and Vestibular Systems The Central Auditory System John F. Brugge Structure and Organization The major ascending auditory pathways of the brain stem and thalamus are shown schematically in Figure 1. (scribd.com)
  • In addition to these pathways, over which impulses originating in the cochlea reach the cerebral cortex, there are corticofugal connections and interneuronal circuits that, together with ascending projections, provide numerous opportunities at all levels of the auditory system for convergence and divergence of afferent input, serial and parallel processing of information, and feedback modulation.

  • cochlear
  • Beginning in the fifth week of development, the auditory vesicle also gives rise to the cochlear duct, which contains the spiral organ of Corti and the endolymph that accumulates in the membranous labyrinth. (wikipedia.org)
  • The present study characterized the behavior of cochlear macrophages after aminoglycoside ototoxicity and also examined the possible role of macrophages in sensory regeneration. (jove.com)
  • Cochlear Nuclei All auditory nerve fibers terminate within the cochlear nuclei (CN), which comprise highly complex groupings of cells that together form a protuberance on the lateral surface of the brain stem at the medullopontine junction. (scribd.com)
  • This highly specialized synaptic arrangement, which is characterized by little convergence from disparate regions of the cochlear partition, is important in preserving temporal information transmitted by auditory nerve fibers. (scribd.com)
  • nucleus
  • The central processes of these neurons are part of tegmentum of pons and terminate in the sensory nuclei of trigeminal nerve: nucleus tractus n. trigemini (pain, temperatura), the zone which applies to cervical segments of the spinal cord, and nucleus sensorius superior (tactile sensitivity).

  • Middle Ear
  • Air reaches the middle ear through the Eustachian tube Eustachian tube [for Bartolomeo Eustachi], a hollow structure of bone and cartilage extending from the middle ear to the rear of the throat, or pharynx, technically known as the pharyngotympanic or auditory tube. (thefreedictionary.com)
  • spinal
  • The first sensory neurons (pseodounipolar ganglionic cells) are located in the trigeminal, or the Gassepovov, site (ganglion trigeminale) - form, homologous spinal site. (scribd.com)
  • There are also connections between the principal auditory centers and the cranial and spinal motor nuclei, which subserve acoustic reflexes, but little is known about them. (scribd.com)
  • signals
  • Central vestibular neurons form identifiable subgroups within the boundaries of classically outlined octavolateral nuclei in primitive vertebrates that are distinct from those processing lateral line, electrosensory, and auditory signals. (readbyqxmd.com)
  • development
  • The research team, led by Dr Walter Marcotti, Royal Society University Research Fellow from the University's Department of Biomedical Science, in collaboration with Professor Karen Steel at the Sanger Institute in Cambridge, discovered that the mutation in miR-96 prevents development of the auditory sensory hair cells. (thefreedictionary.com)
  • internal
  • The vestibulocochlear nerve is accompanied by the labyrinthine artery, which usually branches off from the anterior inferior cerebellar artery (AICA) at the cerebellopontine angle, and then goes with the 8th nerve through the internal acoustic meatus to the internal ear. (wikipedia.org)
