Topographic Mapping of Generators of Somatosensory Evoked Potentials

  • Conference paper
Topographic Brain Mapping of EEG and Evoked Potentials

Abstract

The current interest in somatosensory evoked potentials (SEP) after electrical stimulation of peripheral nerves in humans results from the feasibility of noninvasive studies involving electronic averaging. Such spinal or brain averaged responses do not represent variations of membrane potentials at single neurons, but are compound profiles built up of a sequence of distinct components. Physiological analysis of the corresponding neural generators is important, since data obtained in other mammals cannot be safely extrapolated to man. A robust data base on human responses is essential for their changes in health or disease to be understood and used for clinical diagnosis or investigations of the electrophysiological correlates of psychological processes such as selective attention or memory (see Callaway et al. 1978; Desmedt 1979; Hillyard and Kutas 1983).
