Effects of saccadic eye movements on postural control stabilization

Motriz: Revista de Educacao Fisica, 2013
Several structures of the central nervous system share involvement in both ocular and postural control, but the visual mechanisms in postural control are still unclear.

Suppression of displacement in severely slowed saccades [PDF]

, 2000
Severely slowed saccades in spinocerebellar ataxia have previously been shown to be at least partially closed-loop in nature: their long duration means that they can be modified in-flight in response to intrasaccadic target movements.

When Watching Video, Many Saccades Are Curved and Deviate From a Velocity Profile Model

Frontiers in Neuroscience, 2019
Commonly, saccades are thought to be ballistic eye movements, not modified during flight, with a straight path and a well-described velocity profile. However, they do not always follow a straight path and studies of saccade curvature have been reported ...

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...

Saccadic Impairments in Patients with the Norrbottnian Form of Gaucher’s Disease Type 3

Frontiers in Neurology, 2017
BackgroundChronic neuronopathic Gaucher’s disease type 3 (GD3) is relatively frequent in northern Sweden. Besides multiple other neurological symptoms, horizontal gaze palsy or oculomotor apraxia is common in GD3.ObjectiveTo characterize the saccades in ...

The effects of age and sex on the incidence of multiple step saccades and corrective saccades

Frontiers in Aging Neuroscience, 2022
ObjectiveAlthough multiple step saccades (MSS) is occasionally observed in healthy subjects, it is more pronounced in patients with aging-related neurodegenerative diseases, particularly Parkinson’s disease (PD).

The effect of distractors on saccades and adaptation of saccades in strabismus

Vision Research, 2011
This paper reports two experiments to determine the contribution of the suppressing eye to the generation of saccadic eye movements in constant strabismus. Eye movements were recorded using a Skalar infra-red recorder. Experiment 1 tested six participants with constant strabismus, pathological suppression and no clinically demonstrable binocular single

The Concurrent Programming of Saccades [PDF]

PLOS ONE, 2016
Sequences of saccades have been shown to be prepared concurrently however it remains unclear exactly what aspects of those saccades are programmed in parallel. To examine this participants were asked to make one or two target-driven saccades: a reflexive saccade; a voluntary saccade; a reflexive then a voluntary saccade; or vice versa. During the first
