Various utilizations of VEPs are reviewed by the author's investigations. Short latency VEPs are recordable from the temporal area of the scalp but the electrogenicity of these wavelets which are similar to the auditory brainstem reaction is not yet established. The luminance VEPs has meaning if the defective amplitude or delayed P<SUB>100</SUB> latency is recognized. The pattern VEP including spatial frequency grating is useful as an objective measure for gross estimation visual acuity. Visual recognition and visual selective task appear the P200 and P3oo component respectively from the vertex area. These late potentials are experimentally significant in detecting a high grade vision. For the objective visual field examination, a moving grating target of 5°-10° of subtending angle can evoke a steady state VEP even from a peripheral field and it is interpreted that the potential is elicited from the Y channel. For the determination of stereoptic VEP, the liquid crystal shutter and a real stereo target are used. The amplitudes of binocular VEP are enlarged to about 2 times (√4 times) the monocular VEP.
