The correct answer is the production of language / the perception of language

Language is a mental process of manifesting thought and  essentially of a conscious, meaningful and service-oriented nature  interpersonal contact.

Aphasia is a language disorder that occurs frequently in  cerebrovascular diseases, mainly in stroke  ischemic type (CVA). Language is the form of expression of  people and it happens through speech, writing and gestures. The brain  has a dictionary that is formed during life and that through  complex mechanisms translates words into all forms of  expression. Understanding is obviously part of this process.  

Language is processed in the left cerebral hemisphere of  right-handed people in certain locations with the Broca area and the  Wernicke area. Depending on the location of the injury or the accident  vascular, we can distinguish several different types of aphasias.

Wernicke's aphasia or sensory aphasia:

There is a complete lack of understanding or part of speech  preserved, fluent, but disconnected. An injury in the area of  Wernicke produces huge problems in the ability to  understanding, since this is the place where sounds are transformed into  words.
