Structural analysis of fMRI data: A surface-based framework for multi-subject studies

► The link is made between structural analyses and surface-based analyses. ► Type I error risk is controlled in a non-parametric fashion. ► Individual occurrences of group-level results are available posterior to the detection. ► Robustness to inter-subject variability is good and results are shown relevant. ► A comparison with 3D structural analysis is provided.
