Visual-vestibular interaction in humans during active and passive, vertical head movement.
We studied visual-vestibular interaction (VVI) in 9 normal human subjects using active and passive vertical head rotations. Gain and phase of the vertical vestibulo-ocular reflex (VOR) and visually enhanced vestibulo-ocular reflex (VVOR) were measured for single frequency sinusoidal motion, as well as for sinusoidal motion of continuously increasing frequency, over the range of 0.4 to 4.0 Hz. I...
متن کاملActive Fixation for Scene
It is well-known that active selection of xation points in humans is highly context and task dependent. It is therefore likely that successful computational processes for x-ation in active vision should be so too. We are considering active xation in the context of recognition of man-made objects characterized by their shapes. In this situation the qualitative shape and type of observed junction...
متن کاملEye-head movement coordination: vestibulo-ocular reflex suppression with head-fixed target fixation.
To maintain clear vision, the images on the retina must remain reasonably stable. Head movements are generally dealt with successfully by counter-rotation of the eyes induced by the combined actions of the vestibulo-ocular reflex (VOR) and the optokinetic reflex. A problem of importance relates to the value of the so-called intrinsic gain of the VOR (VORG) in man, and how this gain is modulated...
متن کاملEye movement control during scene viewing: immediate effects of scene luminance on fixation durations.
Recent research on eye movements during scene viewing has primarily focused on where the eyes fixate. But eye fixations also differ in their durations. Here we investigated whether fixation durations in scene viewing are under the direct and immediate control of the current visual input. Subjects freely viewed photographs of scenes in preparation for a later memory test while their eye movement...
متن کاملComputerized dynamic visual acuity with volitional head movement in patients with vestibular dysfunction.
OBJECTIVES Patients with uncompensated vestibular dysfunction frequently report blurred vision during head movement, a symptom termed oscillopsia. One way to measure the functional deficit associated with an impaired vestibulo-ocular reflex is by comparing visual acuity from a baseline condition in which there is no head movement to visual acuity obtained during a dynamic condition with head mo...
