P242 Dynamic time warping distance based connectivity: A new method for resting-state FMRI functional connectivity analysis

Traditionally resting-state networks are analysed with methods implying zero-lag linear dependence between brain regions, i.e. functional connectivity strength between voxel pairs is characterized by the correlation-coefficient of the two measured signal. It is known that the shape and timing of hemodynamic response function differs between brain regions and this introduces artefacts in linear measures. We proposed Dynamic Time Warping (DTW)...
