Visual Evoked Potentials using SmartEP

Visual Evoked Potentials are responses from the cerebral cortex elicited by visual stimulation. These responses are evoked using visual patterns on a light array covering a particular area of the field of view, and are acquired using surface electrodes from the patient’s scalp. VEP testing can help provide information about conditions such as optic
neuritis, optic tumors, retinal disorders, and demyelinating diseases. This Smart Note describes suggested electrode placement, acquisition parameters, and analysis methods, for acquisition of VEP responses using SmartEP on the USB hardware platform.
