Source analysis of single trial MEG data under various noise conditions

Eight data sets were constructed out of the two measurements by either applying the Signal Space Separation noise reduction method (SSS) [5] or not and either adding or leaving the simulated spontaneous activity. Conclusions Our studies showed that source reconstruction results of single trials for...

Description
Summary:	Eight data sets were constructed out of the two measurements by either applying the Signal Space Separation noise reduction method (SSS) [5] or not and either adding or leaving the simulated spontaneous activity. Conclusions Our studies showed that source reconstruction results of single trials for a point-like source can yield localization errors in the range of a few mm. Among the tested methods eLORETA appeared to perform best.
