you are the media you consume.
(My post sounds kind of snippy, but it's not meant to be-- I'm honestly trying to clear up what I'm not understanding. Really.)
And if those three or four five things do not happen.. ok I will mind my busniess doing other things.. but then do not expect any relevant input on this or that function..
SO language could be similar.. but more disperse and networked that the primary visual cortex...I can do a lot of stuff.. you culture pick up.
A pleasure I therefore claim to show, not how men think in myths, but how myths operate in men's minds without their being aware of the fact. Levi-Strauss, Claude
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. A doo run-run-run, a doo run-run
"Emergent Property" is an ontological descriptive term of an observable end-result of a process requiring necessary observable or definable initial conditions AND observable or definable necessary praxiological operations on those conditions. A doo run-run-run, a doo run-run
This two areas you describe are ver well known and do indeed perform certainly clear fucntions in language
But language processing , from writing to devleopment of sentences includes vast areas of the cortex not realted with those two.
Broca andd Wernicke are some kind of focal points for the movement of the mouths/language physcial apparatus and for audotory input.
They are the most external parts of speech processing... something like the primary and final points of the process... Generally, the brain has very specific target areas before proceeding (or the first point of reception from external areas) to project activity to non-brain areas... moto cortex, visual priamry cortex and so on...
So, the ability to speak and process auditory cues comes from the ability of certain parts of the brain to do their primary fucntions by training. If you do not train those areas, they just mind their own business... and still it is only the surface of language processing since it is the part related with output-movement and input-auditory (people do nto know that but a fundamental part of speech is to understand auditory cues, this is why two areas are needed to link the external apparatus with the more complex language processing). But this is only the surface of the processing.. in the same sense the primary visual cortex is only the first stage of visual pattern recognition.
It is my understanding _f_MRI has disproved the old reductionist axiom of a specific location for a specific process. Instead there is a heirarchy of processing where specific areas, such as Broca's, are dedicated to doing the predominate amount of the work while relying or shunting various 'subsidary' tasks to other neuological features, areas. Some of these latter are 'specialists' and some are 'generalists.'

A pleasure, indeed. A doo run-run-run, a doo run-run
It seems that the most perpherial parts of the brain must be hihgly trained at the first stages of development.. and then proceed to get fairly fixed activity. Those areas can be studied in great detail..and the effects of the environment on this areas (learning) can be studied by doing experiments.
Since these specific areas have a high plasticity and highly depend on external input we just guess that the other parts that we see light-up in the fMRI are like mega-complex network of subunits workign hierarchialy and much more plastic than those peripherial areas.
It is really as amazing as you indicate... and more :)
