A more active brain area consumes more oxygen, thus meaning it has a higher demand for oxygen. To meet this increased demand blood flow is directed to the active area (known as ...
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. D 2005 Elsevier Inc. WebHow does fMRI work?
