Is language always localized in the left hemisphere?
For a large majority of people(97% of right-handed people), language is localized in the left hemisphere. However, there
is a larger distribution of language localization among left-handed people(19% in the left hemisphere, 68% in the right hemisphere,
and 13& in both hemispheres).
Nobel Prize winner R. Sperry did research that resulted in the following discoveries:
