The Ultrastructure of the Organ of Corti
1975Publisher Summary This chapter discusses the ultrastructure of the organ of Corti with special emphasis on mechanoreceptors and neural elements. The organ of Corti is a papillary structure resting on the basilar membrane, which is composed of sensorineural and supportive elements.

Specific Proteins of the Organ of Corti
Acta Oto-Laryngologica, 1997The mammalian organ of Corti has achieved a degree of perfection unequaled in other hair cell systems. Although cellular metabolism requires the coordinated action of thousands of proteins, the physical processes underlying auditory transduction in the OC are undoubtedly mediated by a much smaller subset of these.

Serotonergic Innervation of the Organ of Corti
Acta Oto-Laryngologica, 2000The olivocochlear efferent system of the mammalian cochlea, which is divided into two lateral and medial bundles, contains numerous neuroactive substances (acetylcholine, GABA, dopamine, enkephalins, dynorphins and CGRP). These have been located at the brainstem in neurons belonging to the lateral superior olive (lateral efferent system) or in neurons ...

Vulnerability of the Organ of Corti in Poisoning
Acta Oto-Laryngologica, 1966The direct effects of some toxic drugs (kanamycin, dihydrostreptomycin, chloramphenicol, and quinine) upon the organ of Corti have been observed in the guinea pigs. The drug was injected into the middle ear cavity and subsequently reached the organ of Corti through the round window membrane.

Archives of Neurology, 1965
This book is a summarizing account of the studies of Drs. Vinnikov and Titova on the organ of Corti, conducted over the past 22 years. Their approach is predominantly histo- and cytochemical. Most of this work is presented in English for the first time.

A Note on Development of Corti's Organ
Acta Oto-Laryngologica, 1977The structure and postnatal transformation of Kölliker's organ in the cat were studied by means of both light and electron microscopes. Kölliker's organ, which is located in the inner sulcus area of the cochlear duct during embryonic development of the kitten, appeared to undergo a major transformation during the first 30 days after birth. On the level

Finding the impedance of the organ of Corti
The Journal of the Acoustical Society of America, 1991Measurements of the nonlinear response of the basilar membrane to a pure tone are shown to have a simple form for moderate membrane velocities: V(x,f;Vu)/Vu≈[Ṽ(x,f)/Vu]ν(x,f), f⩽fc(x), where the response V is the velocity of the membrane at measurement position x, Vu is the umbo velocity, f is the frequency of the stimulus, and fc(x) is the local ...

Cell coupling in Corti's organ
Brain Research Reviews, 2000The mammalian organ of Corti is responsible for the initial analysis of sound; injury leads to hearing loss. During the last two decades, the characteristics of cellular coupling in this specialized epithelium have been studied. In this review, data on both electrical and mechanical coupling are covered.

Intercellular Junctions in the Organ of Corti
Annals of Otology, Rhinology & Laryngology, 1978The intercellular junctions between adjacent supporting cells and between apposed hair and supporting cells in the organ of Corti of cat and human were studied. At the endolymphatic surface, the intercellular space was closed by a series of tight junctions (zonula occludens), whereas there were no tight junctions at the basilar membrane surface of the

The sensory cells of the organ of Corti are outer hair cells of three to four rows and inner hair cells of a single row, which are fixed on the basal lamina by the supporting cells. The tectorial membrane extends to cover the hair cells and the Hensen’s cell. At the bottom of the sensory cells, there are nerve endings.
