Simultaneous Recording of Visual Evoked Electrical and Magnetic Responses in Man: Increasing the Efficiency of Electrophysiologic Diagnostic Techniques

Abstract

Detection of human visually evoked electrical responses (VER) requires direct electrode contact which results in greater recording variability and artifact. A new alternative method exists, termed the visually evoked magnetic response (MVER), which is free from such complications and interference. A brief review of the development of the technique is presented and a proposal to adapt the method into a potentially useful diagnostic tool is discussed.
