Hi Naveed,

With TR=0.681s, it seems likely that especially pulsation patterns will be seen in the data, which could drive correlations up. Make eroded lateral ventricle masks and run 3dpc to generate a few principal components and take a look. If they seem to have breathing or heart pulse patterns, consider regressing a few PCs (3?). Do you have physiological recordings?
