Freezing of saccades in dopa-responsive parkinsonian syndrome
American Journal of Ophthalmology Case Reports, 2021 Purpose: Ocular motor abnormalities such as abnormal saccades are common in idiopathic Parkinson's disease (PD) and atypical parkinsonian syndrome, such as progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD).

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 ...

Advanced Sensor Research, EarlyView.A wearable capacitive eye tracker for chronic fatigue assessment is presented, utilizing cylindrically shaped capacitive sensors made of a carbon nanotube‐paper composite. By integrating a novel fatigue‐induction protocol with machine learning, the device achieves 0.75‐sensitivity and 0.73‐specificity, providing a practical alternative to existing ...

Journal of Otology, 2023 Background: Saccades are often observed on video head impulse tests (vHIT) in patients with Meniere's Disease (MD) and Vestibular Migraine (VM). However, their saccadic features are not fully described. Objective: This study aims to identify the saccades

Influence of retinal image shifts and extra-retinal eye movement signals on binocular rivalry alternations. [PDF]
PLoS ONE, 2013 Previous studies have indicated that saccadic eye movements correlate positively with perceptual alternations in binocular rivalry, presumably because the foveal image changes resulting from saccades, rather than the eye movement themselves, cause ...

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).

Model simulation studies to clarify the effect on saccadic eye movements of initial condition velocities set by the Vestibular Ocular Reflex (VOR) [PDF]
, 1981 Voluntary active head rotations produced vestibulo-ocular reflex eye movements (VOR) with the subject viewing a fixation target. When this target jumped, the size of the refixation saccades were a function of the ongoing initial velocity of the eye ...

A Method for Detection and Classification of Events in Neural Activity [PDF]
, 2006 We present a method for the real time prediction of punctuate events in neural activity, based on the time-frequency spectrum of the signal, applicable both to continuous processes like local field potentials (LFPs) as well as to spike trains. We test it

Advanced Science, EarlyView.Day‐night cycles trigger sharp relative humidity (RH) shifts in greenhouses. Rapid humidity drops dehydrate Corynespora cassiicola spores, inducing shrinkage, jerking movements, and weakened inter‐spore connections that drive detachment. Wind is essential for dispersal, with even mild airflow enabling rapid pathogen spread. These synergistic effects of

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.
