Power dissipation in the Organ of Corti
The Journal of the Acoustical Society of America, 2017In the cochlea, acoustic energy is transmitted toward the apex through the vibrations of a viscoelastic partition known as the organ of Corti complex. The dimensions of the vibrating structures range from a few hundred micrometers to a few micrometers. Vibrations of micro-structures in viscous fluid are subjected to energy dissipation.

The innervation of the organ of Corti
1983The primary auditory neuron is the bipolar spiral ganglion cell. The axon reaches the medulla through the habenula perforata and the internal auditory meatus. The dendritic process makes contact with the hair cells through the habenula perforata.

The Impedance of the Organ of Corti
1990In previous papers (Zweig 1987, 1988) the impedance of the organ of Corti was deduced from measurements of basilar membrane motion. That impedance is the starting point for this paper. The power transfer between the organ of Corti and its harmonic traveling waves is calculated.

Pinocytosis in the Pillar Cells of the Organ of Corti
Acta Oto-Laryngologica, 1974Electron micrographs are presented showing openings in the head plates of the pillar cells of the organ of Corti. The possibility of fluid transport between the tunnel-spaces and the subtectorial space is inferred from these observations. The capabilities of the pillar cells for fluid transport were further examined through the use of the exogenous ...

The role of thyroxine in the differentiation of the organ of corti
Acta Oto-Laryngologica, 1976The developmental basis of the association of congenital deafness with hypothyroidism observed in several human syndromes was earlier investigated by experiments on mice. The offspring of females with chemically induced hypothyroidism were found to have malformations of the organ of Corti, showing that thyroxine played a role in the differentiation of ...

Ultrastructure of the Organ of Corti in Experimental Hydrops
Acta Oto-Laryngologica, 1988The early ultrastructural changes of the organ of Corti in the guinea pig after obliteration of the endolymphatic sac and duct were examined in a time-sequence study. Initial loss of outer hair cells was followed by inner hair cell degeneration, both starting at the apical part of the cochlea.

Vascular supply to the organ of Corti in man [PDF]
Archives of Oto-Rhino-Laryngology, 1977 The capillary distribution in the basilar membrane and the osseous spiral lamina was studied in 40 human temporal bones. The capillaries were made visible using a histochemical technique for demonstrating alkaline phosphatase activity. High tone sensorineural hearing loss can be explained by capillary distribution, length of a segment in the outer ...

Structural and physiological features of the organ of corti
International Journal of Audiology, 1972Modern methods for structural analysis have during the last decades enriched our knowledge about the organ of Corti. Especially electron microscopy, but also phase contrast microscopy has been important in this development. During the last few years scanning electron microscopy has rapidly become the tool of choise for several of those problems ...

Morphological patterns of the organ of corti in birds
Archiv f�r Klinische und Experimentelle Ohren- Nasen- und Kehlkopfheilkunde, 1971This paper presents the results of an investigation into the avian organ of Corti. Its form and surface area have been estimated and the total number of sensory cells calculated. As described by other authors, the sensory cells occupying the apical and anterior parts of the basilar papilla are tall and slender while those occupying the basal and ...

Nerve Fibers in the Human Organ of Corti
Acta Oto-Laryngologica, 1976In the human cochlea, the following characteristics of nerve fiber arrangements were observed. 1. 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 bundle was small. 2.
