Researchers in California are showing some promising results with a new approach to treating stroke. The scientists are focusing on getting undamaged parts of the brain to _________________________________. In a stroke, a loss of blood supply from a clot, for example, can starve brain tissue of oxygen, and brain cells die.
Each part of the brain is hard-wired for certain functions. One part interprets vision, for example; another moves the left hand. But if undamaged regions can _________________________________killed off in the stroke, then patients might regain lost functions. Thomas Carmichael of the University of California Los Angeles explains that the brain can do that itself, in a limited way.
"The tissue around the damaged region can take over some of the function that was lost. For example, if the region that was lost moved the arm, a portion of the brain that, say, normally moves the face _____________________________can take over some arm movement." Carmichael and his colleagues have been trying to figure out how to improve the process. Using laboratory mice, the scientists induced a stroke in the animals' forelimbs.
"And the rest of the forelimb-movement area is supposed to kick into gear and take over function. And what we found is this tissue that was supposed to kick into gear was instead over-inhibited because it had an accumulation of this inhibitory molecule, GABA."

take over functions impaired by the stroke.
take over the role of brain cells

take over the role the brain cells
which is jesion to the arm region
