Active neurons require more oxygen to burn fuel and thus require the delivery of more oxygenated blood. Webparietal lobe (IPL; BA 40). Overall, our fMRI results suggest that the articulatory motor system is more plastic, hence, more amenable to change because of greater exposure to the L2. By contrast, we propose that our orthography effect is less plastic, hence, less influenced by frequency of exposure to a language system.
