The vestibular system and the visual system coordinate with each other through brain pathways in order to control visual fixation. The ‘ear to eye’ connection is known as the vestibulo-ocular reflex (VOR). The VOR has a critical role of keeping the eyes still during head motion. This is known as gaze stability.

Activities guide students to experience the chal NEW & NOTEWORTHY The so-called vestibulo-sympathetic reflex, as demonstrated by the head-down neck flexion (HDNF) protocol, is present in patients with total bilateral vestibular idiopathic loss, equally in young and old subjects. The origin of the sympathetic effect of HDNF is questioned. Recent animal and clinical studies on the vestibulo-ocular reflex deal with a number of physiological and clinical aspects from which three were chosen for this review: (1) the torsional vestibulo-ocular reflex and its disorders; (2) the otolith contribution to the vestibulo-ocular reflex; and (3) neurotransmitters, neuropharmacological aspects, and medical treatment. Absolut zentral für das Verständnis des Gleichgewichts ist die Verbindung zwischen den Augen und dem Vestibularorgan. In fünf Minuten wird diese komplexe Reg This chapter examined the functional properties and neural substrates of a key vestibulospinal reflex—the vestibular-neck or vestibulocollic reflex (VCR). Functionally, the VCR is a dynamic stabilizing system that shapes head movements, particularly in the critical 1–3 Hz range where the head-neck system exhibits resonant instability.

As the vestibulo-sympathetic reflex is thought to be related to the activation of the otolithic organs, our aim was to assess the vestibulo-sympathetic reflex in a group of patients with bilateral vestibular loss (BVL). We hypothesized that the absence of vestibular signals will abolish the vestibulo-sympathetic response.

The VOR is what allows us to see clearly when we walk, turn our heads, or look out of the window while in a car. So the vestibulo-ocular reflex is a reflex that starts in the vestibular apparatus, in response to head movement, and ends with movement of the eyes. The inner ear, sometimes called the labyrinth, is a marvelous bit of engineering.

This reflex functions to stabilize images on the retinas (in yoked vision) during head motion by producing eye motions in the instructions opposite to head movement, hence maintaining the image on the center of the visual field (s). The vestibulo-ocular reflex (VOR) uses information from the vestibular labyrinth of the inner ear to generate eye movements that stabilize gaze during head movements.

A great deal is known about the anatomy and physiology of neurons that comprise the central leg of the important three-neuron VCR reflex arcs. The righting reflex is not exclusive to humans. A well-known righting reflex in cats allows them to land on their feet after a fall. As a cat falls, it turns its head, rotates its spine, aligns its hindquarters, and arches its back to minimize injury. As the vestibulo-sympathetic reflex is thought to be related to the activation of the otolithic organs, our aim was to assess the vestibulo-sympathetic reflex in a group of patients with bilateral vestibular loss (BVL). We hypothesized that the absence of vestibular signals will abolish the vestibulo-sympathetic response.
