Modes of vestibular habituation. 1973

M H Stroud, and W P Berowitz

An experiment was designed to investigate the effect of different modes of vestibular habituation. Volunteers were divided into two groups differing only in visual fixation. A theoretical explanation of the observed differences in nystagmus speed and frequency of beats between groups is offered. Secondary experiments designed to support the conclusions were performed using optokinetic stimulation with a stationary line for visual fixation. An increase in conjugate tone potential opposed to the unwanted optokinetic stimulus developed. Post-habituation nystagmus patterns appear to depend in considerable part on learned responses originating in the gray matter of the brain.

UI	MeSH Term	Description	Entries
D002150	Caloric Tests	Elicitation of a rotatory nystagmus by stimulating the semicircular canals with water or air which is above or below body temperature. In warm caloric stimulation a rotatory nystagmus is developed toward the side of the stimulated ear; in cold, away from the stimulated side. Absence of nystagmus indicates the labyrinth is not functioning.	Barany Test,Barany's Test,Baranys Test,Caloric Test,Test, Barany,Test, Barany's,Test, Caloric,Tests, Caloric

D014722	Vestibule, Labyrinth	An oval, bony chamber of the inner ear, part of the bony labyrinth. It is continuous with bony COCHLEA anteriorly, and SEMICIRCULAR CANALS posteriorly. The vestibule contains two communicating sacs (utricle and saccule) of the balancing apparatus. The oval window on its lateral wall is occupied by the base of the STAPES of the MIDDLE EAR.
