Kaplan has given wrongly.......................Left handed person always would be Right hemisphere dominant as the fibers crosses in opposite direction at the level of medulla.Always person having opposite hemisphere dominant.As you know, testosterone plays major role before birth in deciding Left handedness.Although Mainly the "Language"IS CONTROLLED BY LEFT HEMISPHERE, EVEN IN LEFT HANDED PERSON...........BUT THE DOMINANCE WOULD BE IN THEM RIGHT HEMISPHERE ONLY.:happy:
