Such compensation mechanism is consistent across species. The paper clearly states that there is not “specialness” in connectivity (in fact, I think, that speech center for complex language doesn’t exist at all. Like conscienceless, complex language is just a emergent property of the cortex).
[ Seems like the paper’s findings are consistent with the Mountcastle’s Common Cortical Algorithm (CCA) hypothesis ]
Um, how I answer depends on what you might be trying to say.
Broca’s and Wernicke’s areas are a thing, with well defined functions and with damage producing well known and stereotyped speech deficits.
Wernicke's area (/ˈvɛərnɪkə/; German: [ˈvɛʁnɪkə]), also called Wernicke's speech area, is one of the two parts of the cerebral cortex that are linked to speech, the other being Broca's area. It is involved in the comprehension of written and spoken language, in contrast to Broca's area, which is involved in the production of language. It is traditionally thought to reside in Brodmann area 22, which is located in the superior temporal gyrus in the dominant cerebral hemisphere, which is the left he...
Broca's area, or the Broca area (/ˈbroʊkə/, also UK: /ˈbrɒkə/, US: /ˈbroʊkɑː/), is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain with functions linked to speech production.
Language processing has been linked to Broca's area since Pierre Paul Broca reported impairments in two patients. They had lost the ability to speak after injury to the posterior inferior frontal gyrus (pars triangularis) (BA45) of the brain. Since then, the approximate region he iden...
The fiber tracks joining areas constrain “what” is processed by the cortical algorithm, with speech functions being located roughly on both ends of the Arcuate_fasciculus.
The arcuate fasciculus (Latin: curved bundle) is a bundle of axons that connects Broca's area and Wernicke's area in the brain. It is an association fiber tract connecting caudal temporal cortex and inferior frontal lobe.
Common understanding has been that the arcuate fasciculus connects two important areas for language use, Broca's area in the inferior frontal gyrus and Wernicke's area in the posterior superior temporal gyrus. The connectivity of the arcuate has been shown to correspond to vari...
Even within an area there are variations in the cortical structure that can be observed with staining and relatively low power microscopes. This is how Brodmann was able to make his maps:
A Brodmann area is a region of the cerebral cortex, in the human or other primate brain, defined by its cytoarchitecture, or histological structure and organization of cells.
Brodmann areas were originally defined and numbered by the German anatomist Korbinian Brodmann based on the cytoarchitectural organization of neurons he observed in the cerebral cortex using the Nissl method of cell staining. Brodmann published his maps of cortical areas in humans, monkeys, and other species in 1909, along ...
Since that time many lines or research have confirmed that these areas have well defined functions.
So - the areas do have functions defined by connectivity, and evolution has tuned the local cortical structures to process the information that is presented by this connectivity.
I acknowledge that my statement was a bit “harsh”
Of course, these areas intervene in the understanding and generation of language, but they are not finalists. If we assume that language processing is pipelined, those zones are just one more “stage” (as, for example, could be the auditory cortex). It is evident that if the auditory cortex is damaged, we will not be able to understand speech.
What makes us different from other mammals is the large volume of our PFC. Basically we are able to “predict” more complex sequences (including complex language). Just that.
