GraFIX: a semiautomatic approach for parsing low- and high-quality eye-tracking data [PDF]

open access: yes, 2014
Fixation durations (FD) have been used widely as a measurement of information processing and attention. However, issues like data quality can seriously influence the accuracy of the fixation detection methods and, thus, affect the validity of our results

Joint Learning of Binocularly Driven Saccades and Vergence by Active Efficient Coding

open access: yesFrontiers in Neurorobotics, 2017
This paper investigates two types of eye movements: vergence and saccades. Vergence eye movements are responsible for bringing the images of the two eyes into correspondence, whereas saccades drive gaze to interesting regions in the scene.

Benefits from vergence rehabilitation: evidence for improvement of reading saccades and fixations

open access: yesFrontiers in Integrative Neuroscience, 2016
We hypothesize that binocular coordination of saccades is based on continuous neuroplasticity involving interactions of saccades and vergence. To test this hypothesis we study reading saccades in young students who were diagnosed for vergence disorders ...

High-field FMRI reveals brain activation patterns underlying saccade execution in the human superior colliculus. [PDF]

open access: yesPLoS ONE, 2010
The superior colliculus (SC) has been shown to play a crucial role in the initiation and coordination of eye- and head-movements. The knowledge about the function of this structure is mainly based on single-unit recordings in animals with relatively few ...

Non spontaneous saccadic movements identification in clinical electrooculography using machine learning [PDF]

open access: yes, 2015
In this paper we evaluate the use of the machine learning algorithms Support Vector Machines, K-Nearest Neighbors, CART decision trees and Naive Bayes to identify non spontaneous saccades in clinical electrooculography tests.

Impaired Initiation But Not Execution of Contralesional Saccades in Hemispatial Neglect

open access: yesBehavioural Neurology, 2002
Patients with unilateral neglect are impaired at making saccades to contralesional targets. Whether this problem arises from a deficit in perception, in planning the saccade or in executing the eye movement or some combination thereof remains unclear. We

Directional interactions between current and prior saccades

open access: yesFrontiers in Human Neuroscience, 2014
One way to explore how prior sensory and motor events impact eye movements is to ask someone to look to targets located about a central point, returning gaze to the central point after each eye movement. Concerned about the contribution of this return to

The effect of vestibulo-ocular reflex deficits and covert saccades on dynamic vision in opioid-induced vestibular dysfunction.

open access: yesPLoS ONE, 2014
Patients with bilateral vestibular dysfunction cannot fully compensate passive head rotations with eye movements, and experience disturbing oscillopsia.

Differential auditory-oculomotor interactions in patients with right versus left sided subjective tinnitus: A saccade study

open access: yesFrontiers in Human Neuroscience, 2013
Subjective tinnitus (ST) is a frequent but poorly understood medical condition. Recent studies demonstrated abnormalities in several types of eye movements (smooth pursuit, optokinetic nystagmus, fixation and vergence) in ST patients.
