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.

Correlated movement of hair bundles coupled to the otolithic membrane in the bullfrog sacculus
Hearing Research, 2009High-speed imaging with a CMOS camera was used to track the motion of multiple hair bundles of the bullfrog sacculus. To maintain the natural degree of intercell coupling, the overlying otolithic membrane was left intact atop the in vitro preparation.

Models of the dynamics of otolithic membrane and hair cell bundle mechanics*
Journal of Vestibular Research, 2001Dynamic behavior of an otolithic membrane (OM) was studied analytically using simplified homogeneous viscoelastic (Kelvin-Voight body) model of the OM. The OM was represented by a thin plate attached to a macular plane. Viscoelastic properties of the OM determine the specific times ( T 1 and T 2 ) and frequency-dependent behavior of the local ...

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.

[Experimental study of streptomycin on 45Ca intake of otolithic membranes].
Zhonghua er bi yan hou ke za zhi, 199845CaCO3 was injected into guinea pigs, and the radioactivity in otolithic membranes of utriculi and sacculi, auditory ossicles and femora was determined by liquid scintillation spectrometry, to study the dynamic effect of streptomycin on calcium content of otolithic membranes, as a means to explore the mechanism of streptomycin ototoxicity. The results

[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

Structure of avian tectorial, otolithic, and cupular membranes.
The Physiologist, 1996Any explanation of cochlear and vestibular micro-mechanics must include the contributions of the tectorial (TM), otholithic (OM), and cupular (CM) membranes. However, unresolved questions about the microarchitectures of these membranes and the types and number of attachments to their underlying sensory areas have hampered the development of micro ...
