Saccades Detection in Optokinetic Nystagmus - a Fuzzy Approach

Fuzzy Clustering Based Methods for Nystagmus Movements Detection in Electronystagmography Signal

The analysis of optokinetic nystagmus (OKN) provides valuable information about the condition of human vision system. One of the phenomena that is used in the medical diagnosis is optokinetic nystagmus. Nystagmus are voluntary or involuntarily eye movements being a response to a stimuli which activate the optokinetic systems. The electronystagmography (ENG) signal corresponding to the nystagmus...

Saccade-like Behaviour in the Fast-Phases of Optokinetic Nystagmus: An Illustration of the Emergence of Volitional Actions from Automatic Reflexes

As a potential exemplar for understanding how volitional actions emerged from reflexes, we studied the relationship between an ancient reflexive gaze stabilisation mechanism (optokinetic nystagmus) and purposeful eye movements (saccades) that target an object. Traditionally these have been considered distinct (except in the kinematics of their execution) and studied independently. We find that ...

Saccadic compensation for reflexive optokinetic nystagmus just as good as compensation for volitional pursuit.

The natural viewing behavior of moving observers ideally requires target-selecting saccades to be coordinated with automatic gaze-stabilizing eye movements such as optokinetic nystagmus. However, it is unknown whether saccade plans can compensate for reflexive movement of the eye during the variable saccade latency period, and it is unclear whether reflexive nystagmus is even accompanied by ext...

Volition and Automaticity in the Interactions of Optokinetic Nystagmus, Infantile Nystagmus, Saccades and Smooth Pursuit

Vertical optokinetic nystagmus and saccades in normal human subjects.

PURPOSE Optokinetic stimulation induces nystagmus that can be used to test the saccadic and visual-tracking systems in some patients with voluntary gaze palsies. The purpose of this study was to characterize vertical optokinetic nystagmus (OKN) in normal human subjects, comparing the dynamic properties of the quick phases with voluntary saccades of similar size and measuring the slow-phase resp...
