Hi All,
I've been using the conn_toolbox to conduct resting BOLD connectivity analyses. The toolbox regresses out ventricular and white matter BOLD, but not mean whole brain BOLD. My understanding is that this approach does a good job removing the effects of cardiac and respiratory cycles, without the risk of introducing false anti-correlations as can happen when one regresses out the mean whole brain BOLD.
Can anyone recommend some good references to support this claim??
Thanks!!!
