Read these two excerpts. What do both of these excerpts show?
A
Players with concussions and players who have never injured their brains showed no difference.
B
The scientists could not tell which part of the brain was working during a task.
C
The scientists found that brains had healed within three days of a concussion.
D
Players who have had concussions use more of their brains to complete tasks than they normally would.
The correct answer is D.
Both excerpts show that players who have experienced concussions may use more of their brains to complete tasks than they normally would, possibly indicating compensatory mechanisms in their brain function after an injury. This suggests an adaptation in brain activity following a concussion.
