Directional interactions between current and prior saccades
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

High-field FMRI reveals brain activation patterns underlying saccade execution in the human superior colliculus. [PDF]
The superior colliculus (SC) has been shown to play a crucial role in the initiation and coordination of eye- and head-movements. The knowledge about the function of this structure is mainly based on single-unit recordings in animals with relatively few ...

Diversity in behavioral responses to sensory stimuli has been attributed to variations in preparatory set. Variability in oculomotor responses toward identical visual stimuli has been well documented, but the neuronal processes underlying this ...

Abstract Background Alternating Hemiplegia of Childhood (AHC) is a severe channelopathy that manifests before 18 months of age, primarily caused by pathogenic variants in the ATP1A3 gene. It is characterized by recurrent and disabling episodes of plegia, dystonia, dysautonomia, along with chronic neurological features and cardiac arrhythmias. About 50%

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

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.

A growing number of studies in vision research employ analyses of how perturbations in visual stimuli influence behavior on single trials. Recently, we have developed a method along such lines to assess the time course over which object velocity ...

Visual System: ‘S’ is not for Saccades [PDF]
Coloured flashes that are visible only to the short-wavelength-sensitive S cones interfere with shifts of visual attention but not with shifts of gaze (saccades). Attention and gaze must therefore be directed by different visual sub-systems.

Seminars in epileptology: How to diagnose status epilepticus in adults and children
Abstract Status epilepticus (SE) can be regarded as the most severe expression of seizure activity characterized by a low probability of spontaneous cessation and mechanisms leading to metabolic and inflammatory derangements with increased risk of brain damage, alterations of neural networks, and potentially life‐threatening systemic complications ...
