ZHANG, Yang; ZHANG, Wenbo; REYNOSO ALCANTARA, Vicenta  and  SILVA-PEREYRA, Juan. Magnetoencephalography: mapping the spatiotemporal dynamics of neuronal activity. Suma Psicol. [online]. 2014, vol.21, n.1, pp.45-53. ISSN 0121-4381.

Magnetoencephalography is a noninvasive imaging technique that measures the magnetic fields on the surface of the head --produced by neuronal currents in brain regions -- and provides highly accurate temporal information. Magnetoencephalography is extremely useful in basic and clinical research as it can also locate the sources of neural activity in the brain. This review chiefly approaches biophysics-related aspects of the method; findings are also discussed on issues such as speech perception, auditory attention and integration of visual-auditory information, which are quintessential in this type of research. Lastly, this review discusses the benefits and limitations of magnetoencephalography and outlines new trends in research with this technique.

Keywords : Cognitive neuroscience; Magnetoencephalography; Current source localization; Speech perception; Attention; Audiovisual integration.
