<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.

Fisheries Research, 1999
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 ...

British Journal of Audiology, 1992
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 ...

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 ...

The Otolithic Membrane Mediates Otolith Organization
The FASEB Journal, 2016Otoconia are small biocrystals that link mechanical forces to the sensory hair cells in the mammalian utricle and saccule, a process essential for sensing linear acceleration and gravity as well as maintaining bodily balance. In fish, structurally similar otoliths mediate both balance and hearing.

Compensation of Otolith Function
Acta Oto-Laryngologica, 1989Horizontal eye displacement in total darkness during lateral tilting about the body axis was examined in 14 patients with unilateral loss of labyrinth function, including 8 cases of positional vertigo or dizziness and 6 symptom-free cases. The change in eye displacement following labyrinthectomy was also studied in 2 cases of labyrinthitis and one case

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.

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.
