Visual Evoked Potential - an overview | ScienceDirect Topics

Visual evoked potentials (VEPs) VEPs are electrical potential differences recorded from the scalp in response to visual stimuli. VEPs to stimuli repeated at low rates are defined as transient VEPs. Steady-state visual evoked potentials (SVEPs) are responses to visual stimuli at relatively high frequencies (above 3.5/s). In normal subjects low-frequency VEPs are widely distributed over the scalp whereas SVEPs are restricted to a region lateral and anterior to the striate cortex.Get price
