Figure 1.
Approximate spatial resolution and temporal resolution differ dramatically across imaging modalities. While fMRI has excellent spatial resolution (sub-centimeter) compared to M/EEG (around a centimeter), it has comparatively poor temporal resolution (seconds versus milliseconds, respectively). Sensor space analysis is based directly on the field topographical patterns (see Section 2.2.2), while source space analysis seeks to map the topographical patterns to the underlying neural sources analysis using ECD or inverse modeling (see Section 2.2.3).
