 When visualizing source reconstructed activity, one can interpolate the activity maps onto a subject-specific anatomical image, using [[reference:​ft_sourceinterpolate]]. Subsequently,​ the interpolated activity can be spatially normalized (using volumetric normalization) using [[reference:​ft_volumenormalise]]. The activity can also be rendered onto the cortical surface. FieldTrip includes a set of template surfaces that have been derived from the Colin27 brain (in MNI152 space) with Freesurfer. These surfaces have been derived from the SPM Canonical Brain. When visualizing source reconstructed activity, one can interpolate the activity maps onto a subject-specific anatomical image, using [[reference:​ft_sourceinterpolate]].
