EEG pros correct answer: Excellent time resolution - Cognitive, perceptual, linguistic, emotional processes are fast and dynamic - For example, consider theta band (4-8 Hz), a slow rhythm but quite fast for our conscious experience - Or consider gamma (30 -80 Hz) Direct indicator of neuronal activity Multidimensional (time, space, frequency, power, phase, connectivity etc) Portability (observing brain in action) Relatively inexpensive EEG cons correct answer: It is not well-s...
