An introduction to magnetoencephalography with some applications.
In this paper an attempt was made to describe the basic principles and procedures involved in recording, noninvasively, magnetic fields from the surface of the head and estimating the intracranial sources that give rise to these fields, presumably the same ones that result in time-varying voltages in the scalp that are known as Evoked and Event-Related Potentials. In addition, data from four experiments are briefly described as a means of providing concrete examples of the applicability of Magnetoencephalographic procedures to research issues of interest to cognitive neuroscientists.
