EEG topography
EEG topography is a neuroimaging technique in which a large number of EEG electrodes are placed onto the head, following a geometrical array of even-spaced points. A special software inside the apparatus' computer, plots the activity on a color screen or printer, by coding the amount of activity in several tones of color (for example, black and blue might depict low EEG amplitude, while yellow and red might depict larger amplitudes).
