Impulsive testing of semicircular canal function

Progress in Brain Research

Abstract

After acute vestibular loss in humans or animals, eye-movement responses to rapid horizontal ipsilesional head rotations ("head impulses") show that there is severe, permanent impairment of the angular vestibulo-ocular reflex. The basis for this appears to be an inhibitory saturation of ipsilesional vestibular nerve, and perhaps vestibular nucleus afferents, in response to high-acceleration, off-direction stimulation of the sole functioning member of any pair of semicircular canals. For the clinician, impulsive testing is an easy and reliable way to identify severe unilateral as well as bilateral impairment of semicircular canal function.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
