Visualisation of domains in the avian tectorial and otolithic membranes with monoclonal antibodies
Hearing Research, 1994The staining patterns observed with six monoclonal antibodies (mAbs) raised in vitro against a fraction derived from the utricular macula were examined with cryosections of the auditory and vestibular organs of the avian inner ear. These antibodies revealed several distinct domains within the gelatinous membranes.

Observation of the Otolithic Membrane by Low-Vacuum Scanning Electron Microscopy
ORL, 2010Untreated specimens (i.e. not fixed, dehydrated or embedded) of the otolithic membrane from the sacculus of guinea pigs were observed at the ultrastructural level by low-vacuum scanning electron microscopy (LVSEM). This technique revealed the presence of a 15- to 20-µm-thick layer of an amorphous substance (the supraotolithic cupula zone) on the ...

Models of otolithic membrane–hair cell bundle interaction
Hearing Research, 2002Transformation of the mechanical input in the chain: acceleration of otolithic membrane (OM)-displacement of the OM gel layer-deflection of hair cell bundle (HCB)-formation of the temporal pattern of polarization was studied using simplified analytical models of these stages of conversion of mechanical stimulus into the HCB electrical response.

[The utricular otolith membrane in the guinea pig].
Zhurnal evoliutsionnoi biokhimii i fiziologii, 1981Several types of otoconia are present in the otolithic membrane of the utricle of fetal, young and adult guinea pigs. These include smooth, transitional and rough otoconia, and a few rhombohedrons. The smooth otoconia are nearly the same numeric fraction in all the specimens. The mean size of otoconia increases only during the course of gestation.

Incorporation Of Radioactive Calcium Into Otolithic Membranes And Middle Ear Ossicles Of The Gerbil
Acta Oto-Laryngologica, 197545CaCl2 was injected into gerbils in single or multiple doses, and the resulting radioactivity in serum, otoconial CaCO3, bone samples, and selected labyrinthine epithelium was determined by liquid scintillation spectrometry. Incorporation into both utricular and saccular otoconia occurred at the rate of 0.06-0.07 nmole Ca++ per day, corresponding to a

Hair-bundle stiffness dominates the elastic reactance to otolithic-membrane shear
Hearing Research, 1993Efficient transduction by acousticolateralis organs requires that a stimulus force principally deflect hair bundles, rather than flex other structural elements. Hair bundles might therefore be expected to provide a large fraction of the impedence to shear motions of otolithic membranes and other accessory structures. We measured the stiffness for shear

The Attachment of the Cupulae, Otolith and Tectorial Membranes to the Sensory Cell Areas
Acta Oto-Laryngologica, 1971Using colloidal iron staining or post-fixation with ruthenium tetroxide it could be evidenced that the interstitial cells on the sensory areas in the inner ear in pigeons produce a fibrillar network sur- rounding every hair bundle of the sensory cells. This network ties the overlying membrane to the surface of the sensory area. The compartments created

[Modeling of the structure and mechanics of the otolith membrane].
Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine, 2002Behavior of otoliths of mammals against static (gravitation and changed pressure in the surrounding endolymph) and dynamic loads was surveyed using analytic and computerized (the finite difference method) models of the otolith membrane (OM). It was presumed that OM consists of gel-like and otoconial layers differing in mechanic and thickness ...

Lectin binding sites in the inner ear membranes. A detailed analysis of the otolithic membranes
1987FITC-labelled lectins with binding specificity to the hexose components of glycoconjugates were used to demonstrate structural difference in the glycoprotein composition of otolithic membranes and ampullar cupulae in chicken embryos, tadpoles and adult specimens of Rana esculenta.

[A study of the otolithic membranes of the saccule and utricle of the guinea pig].
Kosmicheskaia biologiia i aviakosmicheskaia meditsina, 1990By scanning electron microscopy the otolith membranes of the sacculus and utriculus of adult guinea-pigs were examined. The spatial arrangement of otoconia was found to differ from the standard scheme. New forms of imperfect otoconia were detected. Differences in morphological parameters of otoconia in the labyrinthine structures were revealed. Factors
