ABSTRACT

We first present a brief summary of the development of magnetoencephalography (MEG) hard-and software in the Low Temperature Laboratory since the 1980s. In spite of important technical advances in instrumentation during that period, the early MEG data, recorded with single-channel devices by Samuel Williamson and others, are still relevant, as evidenced by later research. However, the whole-head covering MEG instruments with up to 306 superconducting quantum interference device sensors have opened totally new possibilities for studies of temporal aspects of signal processing simultaneously in both hemispheres of the human brain. We briefly review work carried out by our research team on action viewing, cortex muscle coherence, language functions, activation of subcortical structures, and clinical applications of MEG.
