Perceptions as Hypotheses: Saccades as Experiments
Front. Psychology, 2012 If perception corresponds to hypothesis testing (Gregory, 1980); then visual searches might be construed as experiments that generate sensory data. In this work, we explore the idea that saccadic eye movements are optimal experiments, in which data are ...

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 ...

Acta Otorhinolaryngologica Italica, 2019 Driving is not only a physical task, but is also a mental task. Visual inputs are indispensable in scanning the road, communicating with other road users and monitoring in-vehicle devices. The probability to detect an object while driving (conspicuity) is very important for assessment of driving effectiveness, and correct choice of information relevant

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).

Fast saccades toward faces: face detection in just 100 ms.
Journal of Vision, 2010 Previous work has demonstrated that the human visual system can detect animals in complex natural scenes very efficiently and rapidly. In particular, using a saccadic choice task, H. Kirchner and S. J.

Saccadic latency in amblyopia [PDF]
Journal of Vision, 2016 We measured saccadic latencies in a large sample (total n = 459) of individuals with amblyopia or risk factors for amblyopia, e.g., strabismus or anisometropia, and normal control subjects. We presented an easily visible target randomly to the left or right, 3.5° from fixation.

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.

NOTCH2NLC Repeat Expansions in Parkinsonian Disorders: Clinical and Neuroimaging Characteristics
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative disorder caused by NOTCH2NLC GGC repeat expansions, with heterogeneous clinical manifestations, including parkinsonism. Recent studies have identified NOTCH2NLC repeat expansions in patients with Parkinson's disease (PD) and atypical parkinsonism (aPM), suggesting ...

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

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 ...
