intervals and spatial distances, though this conclusion is largely speculative given a lack of comparative studies. In general, the results of this experiment are consistent with a model of temporal processing that has sub-second timing distributed, rather than unified, in the brain. However, cognitive subtraction studies are needed to more rigorously control for the effects of stimulus presentation and subject responses. Diffusion tensor imaging studies are also recommended to examine the sequential connectivity of the areas of activation.
