Evidence for increased visual gamma responses in photosensitive epilepsy.


BACKGROUND A sustained gamma (30-70 Hz) oscillation induced in occipital cortex by high-contrast visual stimulation has been well characterised in animal local field potential recordings and in healthy human participants using magnetoencephalography (MEG). The spatial frequency of a static grating stimulus that gives maximal gamma is also that most likely… (More)
