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 ...

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.

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).

Sagittal otolith morphogenesis asymmetry in marine fishes.
Journal of Fish Biology, 2015This study investigated and compared asymmetry in sagittal otolith shape and length between left and right inner ears in four roundfish and four flatfish species of commercial interest. For each species, the effects of ontogenetic changes (individual age

Otolith shape: a population marker for Atlantic herring Clupea harengus.
Journal of Fish Biology, 2015Otolith shape variation of seven Atlantic herring Clupea harengus populations from Canada, the Faroe Islands, Iceland, Ireland, Norway and Scotland, U.K., covering a large area of the species' distribution, was studied in order to see if otolith shape ...

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 ...

Publisher Summary This chapter reviews the underlying basis for thermal marking, discusses how thermal marks are applied, describes methods for creating mark codes to organize information on otoliths, and notes some of the challenges and drawbacks of the technique. It also discusses current applications of the technique, focusing on salmonid fishes on

Vibration of the Otoliths in a Teleost
2012Fish populations comprise essential parts of marine and freshwater ecosystems as well as being the foundations of considerable human nutrition, industry, and economy. There is growing concern about the possible harmful effects from human-generated sound on fish.

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.
