Lecture 1: how does a neuroscientist view signals and noise in MEG recordings
This video highlights MEG advantages, and describes concepts like field strengths, what happens below 1Hz, coregistration, filter settings or effect of interstimuli interval. Also, several problems are described: single responses are prone to artefacts, we need reasonable localization accuracy and source differentiation, automatic methods bring surprises, etc. Last, strategies to improve performance are outlined, along with wishes for the future (i.e. adjustable whole scalp coverage).
