Fine Structure of the Otolithic Membrane in the Squirrel Monkey
Acta Oto-Laryngologica, 1969 The zonal structures of the otolithic membrane in the squirrel monkey were investigated by electron microscopy, and the different morphology at the different zones was described. The definite existence of the cupular zone and subcupular zone was determined in the subhuman primates and some functional considerations were made.

, 1983 The first reports on the otolithic membrane were done by Tenglia (1925) and Brock (1926). Wittmaak (1956) studied it in the guinea pig, rabbit and dog; Johnsson and Hawkins (1967) in the human and Lindeman (1969 a,b) in the guinea pig. Igarashi and Kanda (1969) recognized cupular zone 1 and cupular zone 2, which are called marginal and medial zones ...

Improved preservation of the otolithic membranes
Proceedings, annual meeting, Electron Microscopy Society of America, 1987 Any explanation of vestibular micromechanics must include the roles of the otolithic and cupular membranes. However, micromechanical models of vestibular function have been hampered by unresolved questions about the microarchitectures of these membranes and their connections to stereocilia and supporting cells.

Ultrastructure of the Otoliths and Otolithic Membrane of the Macula Utriculi in the Guinea PIG
Acta Oto-Laryngologica, 1971 The fine structure of the otoliths and oto-lithic membrane of the macula utriculi in the guinea pig has been studied. It has been confirmed that it adopts a wavy arrangement, being formed of two zones of different electronic densiiy, one marginal and the other medial. Of these zones the former is composed of fibres and an interfibrillar substance.

Journal of Morphology, 1980 AbstractThe sagitta otolithic membrane of Fundulus heteroclitus consists of two different zones. A structured zone (gelatinous layer), which usually exhibits a reticulated or honeycomb‐like architecture, is composed of tightly arranged fibrous material and covers only the sensory region of the macula.

Evolution of Otolithic Membrane. Structure of Otolithic Membrane in Amphibians and Reptilians
Journal of Evolutionary Biochemistry and Physiology, 2004 Otolithic membrane of utricles, saccules, and lagena of amphibians (Bufo bufo, Xenopus laevis, Rana temporaria) and reptiles (Teratoscincus scincus, Agama sanguinolenta, Ophisaurus apodus, Caiman crocodilus) were studied using light and scanning electron microscopy.

Visualisation of domains in the avian tectorial and otolithic membranes with monoclonal antibodies
Hearing Research, 1994 The 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.

Proteins of the gelatinous layer of the trout saccular otolithic membrane
Hearing Research, 1990 Although the otolithic membrane is thought to play an important role in the stimulation of vestibular hair cells, little is known about its chemical composition. We analyzed proteins of the gelatinous layer of this structure from the trout saccule, a probable organ of hearing in fish, by SDS-polyacrylamide gel electrophoresis. A relatively small number

Models of otolithic membrane–hair cell bundle interaction
Hearing Research, 2002 Transformation 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.

Acta Oto-Laryngologica, 1979 The influence of neomycin and streptomycin on the calcium metabolism of the otolithic membranes was investigated in the guinea pig. After chronic treatment with either drug, animals were injected intraperitoneally with radioactive calcium. Retention of calcium in the serum was unaffected by drug treatment, as was the incorporation of radioactivity into
