Unifying Vestibulo-ocular Reflexes
We present an eye/head gaze controller based on recent findings in biological gaze control. Despite the absence of an explicit VOR mechanism the model is able to (i) produce classical VOR responses and (ii) reject head perturbations during the saccadic portion of a gaze shift executed to a remembered target -what is usually attributed to a separate vestibular mechanism. We argue that distinguis...
متن کاملCombined influence of vergence and eye position on three-dimensional vestibulo-ocular reflex in the monkey.
This study examined two kinematical features of the rotational vestibulo-ocular reflex (VOR) of the monkey in near vision. First, is there an effect of eye position on the axes of eye rotation during yaw, pitch and roll head rotations when the eyes are converged to fixate near targets? Second, do the three-dimensional positions of the left and right eye during yaw and roll head rotations obey t...
متن کاملControl of ocular torsion in the rotational vestibulo-ocular reflexes.
Visual stabilization of the retina during rotational head movements requires that in far vision the eyes rotate about the same axis as the head but in opposite direction with a gain close to unity (optimal strategy). To achieve this goal the vestibulo-oculomotor system must be able to independently control all three rotational degrees of freedom of the eye. Studies of the human rotational vesti...
متن کاملOcular toxoplasmosis: the influence of patient age.
The influence of patient age on various features of ocular toxoplasmosis has been a subject of study for many years. The age at which Toxoplasma gondii infection occurs in different populations is related to socioeconomic factors and studies suggest that ocular toxoplasmosis is a more severe disease at the extremes of age. The prevalence of ocular involvement is markedly different between indiv...
متن کاملThe vestibulo-ocular reflex of hypergravity rats.
The vertebrate vestibular system detects linear (otolith organs) and angular (semicircular canals) acceleration. The function of the otolith system is twofold, 1: perception of linear acceleration of the head, and 2: assessment of the spatial orientation of the head relative to the vector of gravity. Because of the latter function, a change of gravity will affect the vestibular input which, in ...
