Online and offline tools for head movement compensation in MEG
Under a Creative Commons license
open access
Highlights
► Head movements have detrimental effects on the statistical sensitivity of MEG data. ► Subjects get real-time feedback to reposition themselves in the MEG. ► Online repositioning keeps the head position consistent within and across sessions. ► Offline regression analysis removes trial-by-trial variance due to head movements. ► These tools are readily applicable to a wide range of tasks and experiments.
