History of Evoked Potential Recording in Humans, potential in nerve, not only found it, but, recording bipolarly with a Thomson’s galvanometer from cerebral cortex in animals, noticed that there was a continuous waxing and waning of cerebral potentials. Superimposed on those waves Caton found potential swings related to sensory stimulation and re

The following is a survey of the major factors, technical, physiologic and pathologic, which influence afferent fiber tract potentials originating in the spinal cord. A bet
