The vestibulo-ocular reflex needs to be fast: for clear vision, head movement must be compensated almost immediately; otherwise, vision corresponds to a photograph taken with a shaky hand. Signals are sent from the semicircular canals using only three neurons, called the three neuron arc.
The vestibular-ocular reflex (VOR) is a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement, thus preserving the image on the center of the visual field. For example, when the head moves to the right, the eyes move to the left, and vice versa.
The symptoms of vestibulocerebellar syndrome vary among patients but are typically a unique combination of ocular abnormalities including nystagmus, poor or absent smooth pursuit (ability of the eyes to follow a moving object), strabismus (misalignment of the eyes), diplopia (double vision), oscillopsia (the sensation that stationary objects in the visual field are oscillating) and abnormal ...
The vestibulo-ocular reflex is a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement in response to neural input from the vestibular system of the inner ear, thus maintaining the image in the centre of the visual field. For example, when the head ...
Triceps reflex — jerking of the forearm when the triceps tendon is hit with a tendon hammer, stimulating the C7 and C6 reflex arcs. Vagovagal reflex — contraction of muscles in the gastrointestinal tract in response to distension of the tract following consumption of food and drink. Vestibulocollic reflex; Vestibulo-spinal reflex
Nucleus of Cajal are one of the named oculomotor nuclei, they are involved in eye movements and reflex gaze coordination. [15] [16] The abducens nerve solely innervates the lateral rectus muscle of the eye, moving the eye with the trochlear nerve. The trochlear solely innervates the superior oblique muscle of the eye. Together, trochlear and ...
The vestibulo-ocular reflex is a reflex that stabilizes gaze when the head is moved. The reflex involves compensatory eye movements driven by inhibitory and excitatory signals. The reflex involves compensatory eye movements driven by inhibitory and excitatory signals.
The flocculus is most important for the pursuit of movements with the eyes. Lesions in the flocculus impair control of the vestibulo-ocular reflex, and gaze holding also known as vestibulocerebellar syndrome. [8] The deficits observed in patients with lesions to this area resemble dose-dependent effects of alcohol on pursuit movements. [9]
