Electrical and magnetic brain recordings: contributions to cognitive neuroscience.
Non-invasive recordings of electrical and magnetic fields from the human brain have revealed spatio-temporal patterns of neuronal activity associated with sensory, motor, and cognitive processes. Recent technical advances allow for improved localization of these activity patterns to specific brain structures. This review considers how electrical and magnetic recordings can help to delineate the neural systems and information processing operations that underlie auditory and visual perception, selective attention, mental chronometry, and memory.
