Cosine similarity between the connectivity maps obtained after GSR and GSS for PCC (blue) and WM (red) seed time courses versus the corresponding GSR fit coefficients. Similarity values are very high (r > .90) when the fit coefficients are close to 1.0 (at which point GSR and GSS are equivalent operations with respect to the seed time course). As the fit coefficient deviates from 1.0, the similarity values decrease for both seeds, rather sharply for the WM seed and relatively slowly for the PCC seed. A Gaussian fit R2 = 0.74 is shown by the black-dashed line.
