Data for each digit were averaged across all rats and acquisitions, and the average RPCC matrix formed. Data presented here show that some parts of the rat forepaw representations are more strongly connected than others, allowing the introduction of the concept of degrees of connectivities within functionally defined brain systems. This information does not seem to be obtainable using fMRI.
