Magnetoencephalography (MEG) is a method of measuring the weak magnetic field
elicited by coherent neuronal activity extracranially. Sponsored by National Science
Council, soon there will be a shared MEG system for social science researchers in
Taiwan. We will discuss the rationale for choosing MEG as a neuroimaging tool to
study human brain function. This talk will also briefly introduce the physiological
origin and the technical background of MEG signal genesis, data acquisition, and data
analysis. Examples of using MEG in social science studies will be presented to
illustrate the power of characterizing the human brain activity during rest, cognition,
and task using this high spectro-spatiotemporal resolution imaging method.
