ABSTRACT
The ongoing background electroencephalogram (EEG) is discussed in Chapter 6 of this book. In this chapter we discuss techniques for extracting from the ongoing EEG measures of the brain’s specific reaction to peripheral sensory stimulation, which are known as
evoked potentials
(EPs). A comprehensive description of the underlying physiological mechanisms may be found in Kandel et al. (2000). Techniques for measuring EPs can also be used to measure sensory nerve potentials that occur before the effects of peripheral stimulation are apparent in the brain. A brief overview of the main technical components necessary to record an EP is provided in Figure 5.1.
