It seems to work better, but there still are many "activation points" outside the brain proper. It also suggests that we're dealing with "comparative inaccuracies," in that, if I wish to use motion as a baseline regressor, I then cannot use the time delay of the hemodynamic response as a regressor, and therefore am forced to allow either one inaccuracy or the other. Am I reading the situation correctly?
