Parametric study of postrotatory nystagmus in normal squirrel monkeys. 1975

M Igarashi, and J C Ledet, and H Miyata

In order to find the most consistent nystagmic parameter following rotation, 16 healthy young adult squirrel monkeys were rotated from 0 to 200 degrees/sec with 1 degrees/sec2 constant angular acceleration and then abruptly stopped. This centric horizontal rotation was performed in a dark room without the eyes being covered. Horizontal eye movement of the postrotatory nystagmic response was recorded: maximum slow and quick phase eye speeds, nystagmic duration, amplitude, number of beats, and maximum average frequencies were studied. The maximum frequency of the nystagmic beats was statistically confirmed at the least variable parameter among the seven parameters. The importance of baseline establishment in the animal nystagmus experiment was emphasized.

D000882	Haplorhini	A suborder of PRIMATES consisting of six families: CEBIDAE (some New World monkeys), ATELIDAE (some New World monkeys), CERCOPITHECIDAE (Old World monkeys), HYLOBATIDAE (gibbons and siamangs), CALLITRICHINAE (marmosets and tamarins), and HOMINIDAE (humans and great apes).

D012399	Rotation	Motion of an object in which either one or more points on a line are fixed. It is also the motion of a particle about a fixed point. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)	Clinorotation,Clinorotations,Rotations
D012453	Saimiri	A genus of the family CEBIDAE consisting of four species: S. boliviensis, S. orstedii (red-backed squirrel monkey), S. sciureus (common squirrel monkey), and S. ustus. They inhabit tropical rain forests in Central and South America. S. sciureus is used extensively in research studies.	Monkey, Squirrel,Squirrel Monkey,Monkeys, Squirrel,Saimirus,Squirrel Monkeys
D012665	Semicircular Canals	Three long canals (anterior, posterior, and lateral) of the bony labyrinth. They are set at right angles to each other and are situated posterosuperior to the vestibule of the bony labyrinth (VESTIBULAR LABYRINTH). The semicircular canals have five openings into the vestibule with one shared by the anterior and the posterior canals. Within the canals are the SEMICIRCULAR DUCTS.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
