aphasia
impairment of language, caused by damage in the left hemisphere either by Broca’s area or Wernicke’s area

controls language expression - an area of the frontal lobe, in the left hemisphere, that directs the muscle movements involved in speech
Wernicke’s area
controls language reception - a brain area involved in language comprehension and expression; in the temporal lobe
