Dynamics of Normalization Underlying Masking in Human Visual Cortex

TL;DR: The neural mechanisms of masking in humans are studied using source-imaged steady state visual evoked potentials and frequency-domain analysis over a wide range of relative stimulus strengths of test and mask stimuli to suggest that contrast normalization accomplishes multiple functional goals.
Journal ArticleDOI

Contrast gain control abnormalities in idiopathic generalized epilepsy

TL;DR: Evidence of hyperexcitability in precisely measured visual evoked responses is identified and the nature of changes in excitation and inhibition that lead to altered responses in human patients with IGE is understood.
Journal ArticleDOI

Attention to Multiple Objects Facilitates Their Integration in Prefrontal and Parietal Cortex

TL;DR: The main objective of this study is to probe the neural interaction that occurs between individual objects when attention is directed toward one or more objects, and to directly measure electrocorticographic steady-state responses corresponding to individual objects and to their interaction using a frequency-tagging technique.
Journal ArticleDOI

EEG source imaging of epileptic activity at seizure onset.

TL;DR: Noninvasive ESI of oscillatory features at ictal onset using 256-channel HD-EEG and high-resolution individual head models can make a useful contribution to the clinical localization of the SOZ in presurgical planning.
