VEP (Visual Evoked Potential)
You will have to sit in a darkened room. In front of you is a screen with a white and black pattern similar to a checkerboard. Additionally you see a light dot which is usually found in the middle or, if checked closely, at the edges. During the entire procedure, you should be looking at the dot, no matter where the black and white pattern moves. The procedure requires you have to a small metal plate attached to the back and middle of your head. Through these electrodes, like during an EEG, retinal activity and optic tracts can be monitored.
