웹Mossy fibers originate from many locations in the brain and spinal cord, and the terminal of each axon is anatomically recognizable as rosettes located within the GL. In mice, the origins of mossy fiber axons are the basilar pontine nuclei, vestibular nuclei, lateral reticular nuclei, and external cuneate nucleus. 웹2024년 4월 9일 · The fibers of the pontine nuclei are all important to motor function, including fiber bundles such as the corticospinal fibers and corticopontine-pontocerebellar system. Specifically, the basilar pons contains all the corticofugal fibers, which include the corticospinal, corticobulbar (or corticonuclear), and corticopontine fibers. [6]
웹2024년 12월 14일 · White matter tracts in the brain, also known as white matter fibers, are classified into three categories:. projection fibers; association fibers; commissural fibers; The white matter can be observed well on T1W, T2W and FLAIR sequences. Some white matter tracts are quite well demonstrated especially on T2W and FLAIR sequences because of … 웹2024년 5월 13일 · Besides, the basal dendritic fibers have a large percentage in layer 5, as shown in Fig. 4C, because the somata reside in layer 5 and basal dendritic fibers are usually distributed around the somata.

Where there was only the basilar fiber in the tunnel of Corti, the internal and tunnel spiral bundle were not observed. In such cases, the number of nerve fibers in the external spiral …
웹1998년 12월 4일 · Responses to tones of a basilar membrane site and of auditory nerve fibers innervating neighboring inner hair cells were recorded in the same cochleae in chinchillas. At near-threshold stimulus levels, the frequency tuning of auditory nerve fibers closely paralleled that of basilar membrane displacement modified by high-pass filtering, …
웹The large lateral zone receives significant input from the basilar pontine nuclei via a primarily crossed pontocerebellar fiber projection. These fibers enter the cerebellum via the middle cerebellar peduncle. Because of this predominant source of afferent fibers, the lateral zone is called the pontocerebellum (Fig. 27.18). huntsman\\u0027s-cup o2The basilar membrane and the hair cells of the cochlea function as a sharply tuned frequency analyzer. Sound is transmitted to the inner ear via vibration of the tympanic membrane, leading to movement of the middle ear bones (malleus, incus, and stapes). Movement of the stapes on the oval window generates a pressure … 더 보기 Electrocochleography (abbreviated ECochG or ECOG) is a technique of recording electrical potentials generated in the inner ear and auditory nerve in response to sound stimulation, using an electrode placed in the ear … 더 보기 ECochG can be performed with either invasive or non-invasive electrodes. Invasive electrodes, such as transtympanic (TT) needles, give clearer, more robust electrical … 더 보기 The CM was first discovered in 1930 by Ernest Wever and Charles Bray in cats. Wever and Bray mistakenly concluded that this recording was generated by the auditory nerve. They named the discovery the "Wever-Bray effect". Hallowell Davis and A.J. Derbyshire … 더 보기 The most common clinical applications of electrocochleography include: • Objective identification and monitoring of Ménière's disease and endolymphatic hydrops (EH) • Intraoperative monitoring of auditory system function during surgery on the brainstem or … 더 보기 The CM, SP, and AP are all used in the diagnosis of endolymphatic hydrops and Ménière's disease.
