Strong Static Magnetic Fields Elicit Swimming Behaviors Consistent with Direct Vestibular Stimulation in Adult Zebrafish
Zebrafish (Danio rerio) offer advantages as model animals for studies of inner ear development, genetics and ototoxicity. However, traditional assessment of vestibular function in this species using the vestibulo-ocular reflex requires agar-immobilization of individual fish and specialized video, which are difficult and labor-intensive. We report that using a static magnetic field to directly s...
متن کاملModulation of Memory by Vestibular Lesions and Galvanic Vestibular Stimulation
For decades it has been speculated that there is a close association between the vestibular system and spatial memories constructed by areas of the brain such as the hippocampus. While many animal studies have been conducted which support this relationship, only in the last 10 years have detailed quantitative studies been carried out in patients with vestibular disorders. The majority of these ...
متن کاملPlenary Lectures PL01 MAGNETIC VESTIBULAR STIMULATION: AN UPDATE
It has been known for decades that Individuals working next to strong static magnetic fields can feel disoriented and vertiginous. Roberts et al. suggested this was due to peripheral vestibular stimulation. Indeed, humans, mice, and zebrafish while inside a strong, static magnetic field, all demonstrate behaviors consistent with peripheral vestibular stimulation. The proposed mechanism for this...
متن کاملMagnetic Vestibular Stimulation in Subjects with Unilateral Labyrinthine Disorders
We recently discovered that static magnetic fields from high-strength MRI machines induce nystagmus in all normal humans, and that a magneto-hydrodynamic Lorentz force, derived from ionic currents in the endolymph and pushing on the cupula, best explains this effect. Individuals with no labyrinthine function have no nystagmus. The influence of magnetic vestibular stimulation (MVS) in individual...
متن کاملPsychoneuroimmuno modulation by controlled vestibular stimulation
Acute stressors (lasting minutes) were associated with potentially adaptive up regulation of some parameters of natural immunity and down regulation of some functions of specific immunity. Brief naturalistic stressors (such as exams) tended to suppress cellular immunity while preserving humoral immunity. Chronic stressors were associated with suppression of both cellular and humoral measures. V...
