Researchers conclude that one hemisphere of the brain can adequately function as if it were doing so for two hemispheres.
People who underwent surgery as children to remove half of their brain were still able to accurately recognize differences between pairs of words or faces.
The research was done to study brain plasticity and perception. Plasticity is when the brain can be molded to reorganize itself in the hemispheric region not injured, or in this case, the only hemispheric region that is there. The participants were able to correctly identify differences between words or faces with more than 80% accuracy.
