Brain■ “My own brain is to me the most unaccountable of machinery—always buzzing, humming, soaring roaring diving, and then buried in mud. And why? What’s this passion for?” said Virginia Woolf, who was so talented at emulating consciousness and the duplicity of the human mind on the page.
__Most writers forget that our brains have anything to do with the words we write, that writer’s block, passion and creativity are not solely the property of our suspicious unconscious. Arranging words in an artfully syntactical manner is but one aspect of language processing—the way human beings process speech or writing and understand it as language, which is made completely by and inside the brain.
__So how do we humans process language? And how does that neural activity translate into the art of writing?

The History of Language Processing
Scientists have been studying the relationship of language and speech for nearly 150 years. In 1861, while Abraham Lincoln was penning his famous inauguration address, French neurologist Pierre Paul Broca was busy discovering the parts of the brain behind Lincoln’s speech—the parts that handle language processing, comprehension and speech production (along with controlling facial neurons).
__What we now know as “Broca’s area” is located in the posterior inferior frontal gyrus. It’s where expressive language takes shape. Broca was the first person to associate the left hemisphere with language, which remains true for most of us today. (This can’t be said about every brain—it’s possible to have a language center on the right side, which is where the language loop lies in the brains of about 30% of left-handed people and approximately 10% of right-handers.)
__Tucked in the back of Broca’s area is the Pars triangularis, which is implicated in the semantics of language. When you stop to think about something someone’s said—a line in a poem, a jargon-heavy sentence—this is the part of your brain doing the heavy work. Because Broca studied patients who had various speech deficiencies, he also gave his name to “Broca’s aphasia, ” or expressive aphasia, where patients often have right-sided weakness or paralysis of the arm and leg due to lesions to the medial insular cortex. (Another of Broca’s patients was a scientist who, after surgery, was missing Broca’s area. Though the scientist suffered minor language impediments, such as the inability to form complex sentences, his speech eventually recovered—which implied some neuroplacticity in terms of where language processing can take place.)
__Ten years after Broca’s discoveries, German neurologist Carl Wernicke found that damage to Broca’s area wasn’t the only place in the brain that could cause a language deficit. In the superior posterior temporal lobe, Wernicke’s area acts as the Broca’s area counterpart, handling receptive language, or language that we hear and process.
__The arcuate fasciculus links Broca’s area to Wernicke’s area. If you damage this bundle of nerves you’ll find yourself having some trouble repeating what other people say.
__Wernicke was also the first person to create a neurological model of language, mapping out various language processes in the brain—speech-to-comprehension, cognition-to-speech and writing-to-reading—a...

how does the processing of language in the human brain change? | Yahoo Answers

There is no one area that provides the language function. There are processors in numerous areas throughout the brain which contribute to and allow the manifestation and understanding of language.
