Broca's Area is associated with the motor cortex.  Dysfunction in this area produces difficulty in enunciating words and sentence production.  Reading and comprehension do not seem to be affected.

Wernicke's Area is associated with the sensory cortex.  Dysfunction produces garbled, profuse, inaccurate, rapid, and incomprehensible speech.  Patients can talk fluently, what they say makes no sense.  

What this suggests is Language Processing, in toto, is an Emergent Phenomena absolutely requiring a basis in the brain's neurology ('hardware') but also ancillary higher-order psycho-cultural ('software') structures.

She believed in nothing; only her skepticism kept her from being an atheist. -- Jean-Paul Sartre
