B Damage to Wernicke’s area produces expressive dysphasia
C Broca’s area is on the right side in most left handed people
D Wernicke’s area controls motor response
A
Left hemisphere is dominant for language in over 95% of right handers and in over 60-70% of left-handers. Wernicke’s area is involved in the understanding of written and spoken language. Wernicke’s area produces receptive aphasia when damaged. Broca’s area is linked with speech production. (but new recent evidence demonstrates that Broca’s area also plays a significant role in language comprehension)
