Effect of Saccadic Adaptation on Sequences of Saccades

Journal of Eye Movement Research, 2012
Accuracy of saccadic eye movements is maintained thanks to adaptation mechanisms. The adaptive lengthening and shortening of reactive and voluntary saccades rely on partially separate neural substrates. Although in daily-life we mostly perform sequences of saccades, the effect of saccadic adaptation has been mainly evaluated on single saccades.

Voluntary Saccade Training Protocol in Persons With Parkinson’s Disease and Healthy Adults

Frontiers in Aging Neuroscience, 2019
Background: Voluntary saccade function gradually decreases during both the progression of Parkinson’s disease (PD) and neurologically healthy adult aging. Voluntary saccades display decreased length and increased saccade latency, duration, and the number

Focal seizures during simulated driving: A pilot study

Epilepsia, EarlyView.
Abstract Cars are increasingly equipped with technology that can be used to analyze driver behavior and alertness, often referred to as driver monitoring systems (DMS). Although initially mainly used to track drivers' attention, DMS are now expanding in the hope of detecting additional forms of driver impairment that may jeopardize driving, such as ...

Pediatric sensorimotor cortical responsiveness to intracerebral stimulation during stereoelectroencephalographic monitoring: Age effects and area specificity

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to determine how age influences clinical responsiveness to intracerebral electrical stimulation (IES) in children across primary and secondary sensorimotor cortices and to assess age effects on response complexity and area‐specific responsiveness.

The antisaccade task as a research tool in psychopathology: A critical review [PDF]

, 2006
The antisaccade task is a measure of volitional control of behavior sensitive to fronto-striatal dysfunction. Here we outline important issues concerning antisaccade methodology, consider recent evidence of the cognitive processes and neural mechanisms ...

CaMKIIβ insufficiency disrupts cortical networks, producing aberrant low‐gamma oscillations and seizure susceptibility

Epilepsia, EarlyView.
Abstract Objective Pathogenic variants in the calcium/calmodulin‐dependent protein kinase II B gene (CAMK2B) have been associated with neurodevelopmental disorders, including epilepsy, yet the mechanisms underlying cortical dysfunction remain largely unclear.

Localization of a single tactile stimulus during saccadic eye movements

i-Perception
To localize tactile events in external space, our perceptual system must transform skin-based locations into an external frame of reference. Such a transformation has been reported to involve reference frames that are unrelated to tactile sensations ...

Quick Models for Saccade Amplitude Prediction

Journal of Eye Movement Research, 2009
This paper presents a new saccade amplitude prediction model. The model is based on a Kalman filter and regression analysis. The aim of the model is to predict a saccade’s am-plitude extremely quickly, i.e., within two eye position samples at the onset ...

An n‐of‐1 gene‐directed drug repurposing trial for an ultrarare genetic condition

Epilepsia, EarlyView.
Abstract Objective Gain‐of‐function (GoF) variants in the KCNC1 potassium channel subunit gene (Kv3.1) cause motor/cognitive delays and hypotonia and have been associated with seizures. Fluoxetine has inhibitory effects on Kv3.1. However, open‐label nonrandomized administration is insufficient to guide clinical decision‐making in ultrarare conditions ...

Epilepsy syndromes classification

Epilepsia Open, EarlyView.
Abstract Epilepsy syndromes are distinct electroclinical entities which have been recently defined by the International League Against Epilepsy Nosology and Definitions Task Force. Each syndrome is associated with “a characteristic cluster of clinical and EEG features, often supported by specific etiologic findings”.
