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

PLoS 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]

, 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.

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

Frontiers 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.

Directional interactions between current and prior saccades

Frontiers 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

Spatial frequency processing in the central and peripheral visual field during scene viewing

, 2016
Visuospatial attention and gaze control depend on the interaction of foveal and peripheral processing. The foveal and peripheral regions of the visual field are differentially sensitive to parts of the spatial-frequency spectrum.

Mutations in the Key Autophagy Tethering Factor EPG5 Link Neurodevelopmental and Neurodegenerative Disorders Including Early‐Onset Parkinsonism

Annals of Neurology, EarlyView.
Objective Autophagy is a fundamental biological pathway with vital roles in intracellular homeostasis. During autophagy, defective cargoes including mitochondria are targeted to lysosomes for clearance and recycling. Recessive truncating variants in the autophagy gene EPG5 have been associated with Vici syndrome, a severe early‐onset neurodevelopmental

Slowed vertical saccades as a hallmark of hereditary spastic paraplegia type 7

Annals of Clinical and Translational Neurology, 2019
Anecdotal oculomotor disturbances have been described in spastic paraplegia type 7 (SPG7). We investigated oculomotor and vestibular dysfunction in five patients with genetically verified SPG7.

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

Frontiers 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 ...
