Document Summary
Severity of symptoms is going to depend on the size of the lesion and location of lesion. 1)receptive aphasia: have problems receiving/comprehending language: integrative aphasia: problems with comprehension of language, as well as the formation of language, expressive aphasia: problems getting language out (the expression of language) Language comes into the temporal lobe (primary receptive area for sound) and decoded/integrated in. Wernickes area (posterior temporal lobe), and then to produce speech, has to go to motor cortex. Brocas area is the area infront of motor cortex. Problems in wernickes lead to receptive, while problems in brocas leads to expressive aphasia. Pure word deafness: problems in relating incoming sounds into representations which allow the understanding of discourse. Can hear a sound, have problems deciphering/distinguishing it into language and not just sound. Generally caused by some sort of brain damage in the primary receptive area in the temporal lobe.
