If Darren's brain is like that of most people?

Along with left- or right-handedness, the hemisphere of the brain where language capacity resides is likely predetermined. Researchers have now shown that with age, language capacity in the brain becomes more evenly distributed between hemispheres.However if Darren is an adult then like most nearly all adults, the language center of the brain resides in the left hemisphere. Being left or right brained does not determine what part of your brain controls language.
