[HTML][HTML] Dynamic network drivers of seizure generation, propagation and termination in human neocortical epilepsy

AN Khambhati, KA Davis, BS Oommen… - PLoS computational …, 2015 - journals.plos.org
The epileptic network is characterized by pathologic, seizure-generating ‘foci’ embedded in
a web of structural and functional connections. Clinically, seizure foci are considered optimal …

Eye orientation during static tilts and its relationship to spontaneous head pitch in the laboratory mouse

BS Oommen, JS Stahl - Brain research, 2008 - Elsevier
Both eye position and head orientation are influenced by the macular (otolith) organs, via
the tilt maculo-ocular reflex (tiltMOR) and the vestibulo-collic reflexes, respectively. The …

The influence of future gaze orientation upon eye-head coupling during saccades

BS Oommen, RM Smith, JS Stahl - Experimental Brain Research, 2004 - Springer
Mammals with foveas (or analogous retinal specializations) frequently shift gaze without
moving the head, and their behavior contrasts sharply with “afoveate” mammals, in which eye …

Recurring functional interactions predict network architecture of interictal and ictal states in neocortical epilepsy

AN Khambhati, DS Bassett, BS Oommen, SH Chen… - eneuro, 2017 - eneuro.org
Human epilepsy patients suffer from spontaneous seizures, which originate in brain regions
that also subserve normal function. Prior studies demonstrate focal, neocortical epilepsy is …

Eye Movements of the Murine P/Q Calcium Channel Mutant Tottering, and the Impact of Aging

JS Stahl, RA James, BS Oommen… - Journal of …, 2006 - journals.physiology.org
Mice carrying mutations of the gene encoding the ion pore of the P/Q calcium channel (Cacna1a)
are an instance in which cerebellar dysfunction may be attributable to altered …

Idiosyncratic variations in eye–head coupling observed in the laboratory also manifest during spontaneous behavior in a natural setting

ZC Thumser, BS Oommen, IS Kofman… - Experimental Brain …, 2008 - Springer
The tendency to generate head movements during saccades varies from person to person.
Head movement tendencies can be measured as subjects fixate sequences of illuminated …

Amplitudes of head movements during putative eye-only saccades

BS Oommen, JS Stahl - Brain research, 2005 - Elsevier
The mechanisms allowing humans and other primates to dissociate head and eye movements
during saccades are poorly understood. A more precise knowledge of head movement …

[PDF][PDF] Image-shifting optics for a nystagmus treatment device.

RM Smith, BS Oommen… - Journal of …, 2004 - media.kenanaonline.com
Acquired pendular nystagmus (APN) complicates multiple sclerosis and other neurological
disorders, causes visual impairment, and is often refractory to available treatments. Vision …

Overlapping gaze shifts reveal timing of an eye–head gate

BS Oommen, JS Stahl - Experimental brain research, 2005 - Springer
The ability to dissociate eye movements from head movements is essential to animals with
foveas and fovea-like retinal specializations, as these species shift the eyes constantly, and …

[PDF][PDF] Application of adaptive filters to visual testing and treatment in acquired pendular nystagmus.

RM Smith, BS Oommen, JS Stahl - Journal of Rehabilitation …, 2004 - kenanaonline.com
Acquired pendular nystagmus (APN) complicates multiple sclerosis and other neurological
disorders, causes visual impairment, and frequently resists treatment. Vision could be …
