Correction of Disturbances Caused by Temporary and Continuous Head Movements

This study was performed to assess the effectiveness of the spatiotemporal Signal Space Separation (tSSS) and head movement compensation (MC). Continuous MEG data were acquired from 20 adult and 10 child subjects in four conditions: (1) A reference with a static head position, (2) the subject changed the head position twice, (3) the subject moved the head constantly, and (4) two magnetized pieces were attached to the scalp and the subject moved the head. The recordings were repeated with two whole-head MEG systems.
