Decoding Steady-State Visual Evoked Potentials From Electrocorticography

Frontiers in Neuroinformatics, 2018
We report on a unique electrocorticography (ECoG) experiment in which Steady-State Visual Evoked Potentials (SSVEPs) to frequency- and phase-tagged stimuli were recorded from a large subdural grid covering the entire right occipital cortex of a human ...

Visual Evoked Potentials and Glaucoma

Asia-Pacific Journal of Ophthalmology, 2018
Visual evoked potentials (VEP) can be used to assess the function of the visual system objectively. Research on VEP testing as a method of glaucoma evaluation has been performed for many years. Pattern VEP has shown good specificity and sensitivity in the detection of glaucoma in some studies, but other studies have not shown similar efficacy ...
