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.

The task is an action or activity that the subject does in order to produce a particular activation of the brain. For example, moving the right hand fingers continuously is a motor task that "activates" the brain cortex in the left frontal lobe. WebFunctional magnetic resonance imaging or functional MRI ( fMRI) measures brain activity by detecting changes associated with blood flow. [1] [2] This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.

WebFunctional MRI (fMRI) is used to evaluate subtle regional blood flow changes in the brain cortex that occur during patients performing specific tasks. WebBecause the changing distribution of oxygenated blood in the brain is known to correlate with neural activity, fMRI can be used to image the parts of a patient’s brain that become active and inactive during various tasks. This makes fMRI a very useful tool for neuroscientists and psychologists. [Attribution and references] Sort by: Top Voted
