ILAE neuroimaging task force highlight: MRI detection of early life epilepsy caused by focal cortical dysplasia

Epileptic Disorders, EarlyView.
Abstract The ILAE Neuroimaging Task Force aims to publish educational case reports that highlight basic aspects of neuroimaging in epilepsy consistent with the ILAE's educational mission. Here, we describe a case series of three neonates with focal cortical dysplasia (FCD)‐related drug‐resistant epilepsy who underwent surgical intervention. The purpose

Impaired Initiation But Not Execution of Contralesional Saccades in Hemispatial Neglect

Behavioural Neurology, 2002
Patients with unilateral neglect are impaired at making saccades to contralesional targets. Whether this problem arises from a deficit in perception, in planning the saccade or in executing the eye movement or some combination thereof remains unclear. We

Differential auditory-oculomotor interactions in patients with right versus left sided subjective tinnitus: A saccade study

Frontiers in Human Neuroscience, 2013
Subjective tinnitus (ST) is a frequent but poorly understood medical condition. Recent studies demonstrated abnormalities in several types of eye movements (smooth pursuit, optokinetic nystagmus, fixation and vergence) in ST patients.

Lateralizing value of ictal head turning: A systematic review and meta‐analysis

Epileptic Disorders, EarlyView.
Abstract Objective To elucidate the lateralizing value of ictal head turning in focal epilepsy and provide guidance for interpreting ictal semiology within the framework of presurgical evaluation. Methods We conducted a systematic review of ictal head turning. We included studies reporting ictal head turning (versive, nonversive, and gyration) captured

The effect of vestibulo-ocular reflex deficits and covert saccades on dynamic vision in opioid-induced vestibular dysfunction.

PLoS ONE, 2014
Patients with bilateral vestibular dysfunction cannot fully compensate passive head rotations with eye movements, and experience disturbing oscillopsia.

Directional interactions between current and prior saccades

Frontiers in Human Neuroscience, 2014
One way to explore how prior sensory and motor events impact eye movements is to ask someone to look to targets located about a central point, returning gaze to the central point after each eye movement. Concerned about the contribution of this return to

Structural neural networks subserving oculomotor function in first-episode schizophrenia [PDF]

, 2004
BACKGROUND: Smooth pursuit and antisaccade abnormalities are well documented in schizophrenia, but their neuropathological correlates remain unclear. METHODS: In this study, we used statistical parametric mapping to investigate the relationship between

Slowed vertical saccades as a hallmark of hereditary spastic paraplegia type 7

Annals of Clinical and Translational Neurology, 2019
Anecdotal oculomotor disturbances have been described in spastic paraplegia type 7 (SPG7). We investigated oculomotor and vestibular dysfunction in five patients with genetically verified SPG7.

Saccade learning with concurrent cortical and subcortical basal ganglia loops [PDF]

, 2013
The Basal Ganglia is a central structure involved in multiple cortical and subcortical loops. Some of these loops are believed to be responsible for saccade target selection.

The Fixation and Saccade P3

PLoS ONE, 2012
Although most instances of object recognition during natural viewing occur in the presence of saccades, the neural correlates of objection recognition have almost exclusively been examined during fixation. Recent studies have indicated that there are post-saccadic modulations of neural activity immediately following eye movement landing; however ...
