What determines the direction of microsaccades?

open access: yesJournal of Eye Movement Research, 2010
During visual fixation, our eyes are not entirely still. Instead, small eye movements, such as microsaccades, can be observed. We here investigate what determines the direction and frequency of these microsaccades, as this information might help to ...

Precision therapies for genetic epilepsies in 2025: Promises and pitfalls

open access: yesEpilepsia Open, EarlyView.
Abstract By targeting the underlying etiology, precision therapies offer an exciting paradigm shift to improve the stagnant outcomes of drug‐resistant epilepsies, including developmental and epileptic encephalopathies. Unlike conventional antiseizure medications (ASMs) which only treat the symptoms (seizures) but have no effect on the underlying ...

Compensatory saccades in head impulse testing influence the dynamic visual acuity of patients with unilateral peripheral vestibulopathy1 [PDF]

open access: yes, 2016
BACKGROUND Both the dynamic visual acuity (DVA) test and the video head-impulse test (vHIT) are fast and simple ways to assess peripheral vestibulopathy.

Case report: Spiller syndrome initially mimicking vestibular neuritis

open access: yesFrontiers in Neurology, 2023
Spiller syndrome is a rare subtype of medial medullary infarction (MMI). Herein, we report on a patient with progressing stroke who presented with the initial features of acute peripheral vestibulopathy and MMI (Spiller syndrome), as confirmed by ...

Absence seizures: Update on signaling mechanisms and networks

open access: yesEpilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Visual attention with implications for unilateral spatial neglect. [PDF]

open access: yes, 1992
Recent models of visual attention (eg. Rizzolatti et al., 1987) have suggested that a similar system orients visual attention as is used to produce a saccadic eye movement. This thesis provides further support for the link between the attentional and eye

Visual attention is not deployed at the endpoint of averaging saccades.

open access: yesPLoS Biology, 2018
The premotor theory of attention postulates that spatial attention arises from the activation of saccade areas and that the deployment of attention is the consequence of motor programming.

Effectiveness and safety of implantable vagus nerve stimulation in people with primary generalized tonic–clonic seizures

open access: yesEpilepsia Open, EarlyView.
The impact of prompt diagnosis and treatment, and early predictors of outcome severity in this cohort. Abstract Objective Most therapies for drug‐resistant epilepsy (DRE) focus on focal‐onset seizures, the most common seizure types. Studying primary generalized tonic–clonic seizures (PGTCS) is more challenging due to diagnostic and recruitment ...

Using Video Head Impulse Testing to Unmask Covert Saccades in Compensated Vestibular Neuritis (Figures 1 and 2) [PDF]

open access: yes, 2017
This is a 30-year-old woman who experienced the acute vestibular syndrome (prolonged vertigo for >24 hours, nausea, unsteadiness, spontaneous nystagmus, head motion intolerance) and was diagnosed with vestibular neuritis.

No Evidence That Frontal Eye Field tDCS Affects Latency or Accuracy of Prosaccades

open access: yesFrontiers in Neuroscience, 2018
Transcranial direct current stimulation (tDCS) may be used to directly affect neural activity from outside of the skull. However, its exact physiological mechanisms remain elusive, particularly when applied to new brain areas. The frontal eye field (FEF)
