In this work, a method is presented for the transformation of MEG recordings to a standard sensor position. For the case of an 148 channel magnetometer array, the algorithm was evaluated using simulations as well as phantom head recordings. It turned out that the method is very robust and yields accurate results regardless of the position of the field(More)
OBJECTIVES A problem with the topographic mapping of MEG data recorded with axial gradiometers is that field extrema are measured at sensors located at either side of a neuronal generator instead of at sensors directly above the source. This is problematic for the computation of event-related desynchronization (ERD) on MEG data, since ERD relies on a(More)
