A model of otolith stimulation
Biological Cybernetics, 1989A new model of otolithic stimulation by linear acceleration is presented and compared to previous models, based upon anatomical evidence and on the ability of normal subjects to sense the direction of a linear acceleration vector acting in the coronal plane (roll-tilt perception).

Publisher Summary Positional reflexes from the labyrinth upon the limbs are shown to be asymmetric in their effects. The combination of labyrinth reflexes with neck reflexes serves to provide stabilization of the trunk. The pattern of labyrinth reflexes is altered by acute cerebellectomy and by destroying one labyrinth. The otolith apparatus responds

Piezoelectric Property of Otoliths
Science, 1967Otoliths of two species of bony fishes have been found to be piezoelectric. Hence, in theory, they constitute a mechanism for depth perception or frequency analysis of sound waves, or both.

Otolithic signals contribute to; (1) perception of orientation and linear motion, (2) generate compensatory eye movements in response to linear acceleration of the head and (3) participate in the co-ordination of movement and balance. Tests of these functions shown to be useful in identifying clinical disorders have been reviewed: (1) Evaluation of ...

In order to investigate otolith function, horizontal eye displacement in total darkness during tilting laterally about body axis was examined in 23 normal subjects and 29 patients with vestibular lesions. The mean and standard deviation of this eye displacement in normal subjects were 18.9 + 6.1 degrees at 15 degrees of body-tilt.

<div class="htmlview paragraph">The otolith organs are the linear motion sensors of the mammalian system. As part of the vestibular system these small organs are located in the inner ear. Mathematically modeled, they consist of an overdamped second-order system with elastic, viscous damping, and mass elements.

Two technically simple tests, vestibular evoked myogenic potential (VEMP) and subjective visual vertical/horizontal (SVV/H) test, have the potential to transform otolith function testing from the research laboratory to the outpatient clinic. Cervical- and ocular-VEMPs are short latency surface potentials produced through the activation of saccular and ...

Otolith thermal marking is a widely used technique for identifying origins of hatchery-produced salmonids, using short-term temperature fluctuations to induce distinctive structural marks onto the otoliths of incubating fish. This has clear economic advantages over individual tagging techniques, where fins are clipped or materials inserted into the ...

Ultrastructure of the Otoliths and Otolithic Membrane of the Macula Utriculi in the Guinea PIG
Acta Oto-Laryngologica, 1971The 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.
