Document Summary

The wernicke-geschwind model describes the language network. Major components i(cid:374)clude broca"s area, wer(cid:374)ickes"s area, a(cid:374)d the arcuate fasciculus, which connects them. This model is an over-simplifications of the language network: auditory inputs: (cid:894)spoke(cid:374) (cid:449)ords(cid:895) (cid:373)o(cid:448)e fro(cid:373) the auditor(cid:455) corte(cid:454) to wer(cid:374)icke"s area, visual inputs: (written words) move from the occipital cortex through the angular gyrus to. Wer(cid:374)icke"s area: after an analysis of the input: la(cid:374)guage i(cid:374)for(cid:373)atio(cid:374) (cid:373)o(cid:448)es to the broca"s area (cid:448)ia the arcuate fasciculus, broca"s area: is necessary to create the production of a response to the input. * fi(cid:374)all(cid:455), broca"s area outputs the articulatio(cid:374) of a respo(cid:374)se through the (cid:373)otor corte(cid:454), (cid:449)hich then passes the signal to the muscles needed to produce the response (ex. There is an elaborate and extensive network and extensive network of language areas outside the wernicke-geschwind model. Nouns and verbs are located in different parts of the brain.
