Abstract
Mapping of the electrical activity of the brain may be divided in two main categories: analysis in the time domain and analysis in the frequency domain. A difference in the case of mapping as compared to conventional EEG/EP recordings is the fact that data of both these domains are transferred to the spatial domain by measuring the amount of activity over a restricted number of electrode sites and using interpolative methods for interelectrode points (pixels) to produce a continuous visual image. In the time domain map features of raw EEG/EP data are presented, as shown in Table 2. In the frequency domain, a computer algorithm (as described in Sect. 5.4) converts EEG data to a series of frequency components and their associated amplitudes.
