Quantifying the brain's sheet structure with normalized convolution

A recent debate on the existence of ‘sheet structures’ in the brain has gained much attention from the neuroscience and diffusion MRI (dMRI) communities (Catani et al., 2012; Wedeen et al., 2012a; Wedeen et al., 2012b). While the term sheets had already been suggested in several contexts before (Kindlmann et al., 2007; Schultz et al., 2010; Smith et al., 2006; Vilanova et al., 2004; Yushkevich et al., 2008; Zhang et al., 2003), Wedeen et al. (2012b) proposed a different and specific definition of brain sheet structure: a composition of two sets of tracts that locally cross each other on the same surface.
