message: Is this the same thing as the motor speech area?  If so, we should probably include it, simply because eponyms are no longer in vogue.

message: Quoting from Science Daily:
:In the new study, the researchers non-invasively scanned the brains of three chimpanzees as they gestured and called to a person in request for food that was out of their reach. Those chimps showed activation in the brain region corresponding to Broca's area and in other areas involved in complex motor planning and action in humans, the researchers found. - Science Daily, February 28, "Chimps May Have A 'Language-ready' Brain"

thread_title: Article

message: I've decided to grace this article with my presence sometime in the near future.  In the meantime, for anyone reading along, here are some of the main issues that I think need to addressed (these are things that I will be addressing in my edits to come, but I'm listing them here just in case anyone wants to get started early, or in case anyone disagrees).
*The section Case study is totally unjustified, it gives undue weight to a single study.  Will get rid of it and integrate that reference into other areas.
*Aphasia section needs rewritten; current version focuses mostly on comparison with other aphasias, which belongs (and is already present in) the main Aphasia article.  Section should say more about Broca's aphasia and doesn't need the table (which is simply copied from here anyway).
*Broca's area revisited is also just about one study (Dronkers et al, 2007) and should be rewritten as a summary of relevant literature, not just the one study.  Another relevant paper is 
*Stuff I mentioned above about how there needs to be more coverage of the literature that suggests Broca's area is a workspace of working memory, rather than a syntax-specific or even language-specific area. Relevant papers include:

**And, of course, for a counterpoint:  (and some earlier papers cited in this one)

replies: text: I'll admit I'm guilty of not reading this talk page before making some of my edits.  I have to agree with a lot of what this editor says, although the presence of information on aphasia (especially Broca's aphasia) is not contraindicated on this page just because this information appears elsewhere in the encyclopedia.  I do agree that refining the section to more specifically elucidate the nature of Broca's aphasia is probably warranted, but I do not think it is possible to do so without mentioning and comparing the other forms of aphasia to Broca's aphasia.  As an aside, the section on the origin of language probably should be truncated; I made a number of additions to this area which were (in my mind justifiably) removed, and a link to the main article on the origins of language along with a very short stub describing, briefly, the relevence of Broca's area to the discussion would suffice in my opinion.

thread_title:  Areas for improvement 

message: I have undone this addition for the following reasons:
*It's not clear what it means. "This area is also crucially involved in the recognition of recursive rules, the only one admitted in human languages"---what does "the only one" refer to? And what is the nature of the region's involvement?
*Citing a full book without giving page or chapter numbers is not really helpful, as it would be difficult to find the relevant passage to verify this.
*If this is a claim based on one experiment, then it doesn't belong in the article anyway; for a topic like this, we really should be limiting ourselves to sources more like review articles, where the claims are widely replicated and are agreed upon. Mentioning every neuroscience result that implicates Broca's area (or any region) in anything would quickly get beyond the scope of the article.
Also, for what it's worth, the link provided was dead. rʨanaɢ (talk) 02:48, 26 October 2014 (UTC)

thread_title:  External links modified 

message: From May 2010 until November 2018 I've been experiencing increasingly frequent and increasingly severe Neurological symptoms: Brain Seizures, Dissociative Fugues - more commonly known as Fugue States - Broca's Aphasia in both my speech and my writing, and just in my last episode, really loud Tinnitus - ringing in my ears - severe dizziness leading to severe nausea, and numbness in my feet and lips.  Four CT Scans, an MRI and a bunch of physical stroke exams which test for asymmetries in one's movements or physical strength make abundantly clear that I've never had brain cancer, a stroke, hemorrhage nor blood clot.
All my doctors other than just last week my new Neurologist have been totally stymied.
This is so far speculation on the parts of myself and my Neurologist.  She suggested I have B12 Anemia due to my last ER visit having complained of numbness in the soles of both my feet as well as both my lips.  Such Anemia is known to cause numbness in one's feet and hands.
If this turns out to be the case for me, in my case that's likely to be Pernicious Anemia, as my Great-Grandfather - my mother's father's father - died of it before the discovery of Liver Therapy.  It's three inventors shared the 1934 Medicine Nobel.  Further research found that the essential component of liver was at first red blood cells, then the Methylcobalamin form of Vitamin B12, and at some point the ultimate cause of PA was found to be a deficiency of a stomach enzyme called "Intrinsic Factor".  If there's not enough IF in the stomach, the small intestine won't be able to absorb Methylcobalamin.  The best treatment is now Vitamin B12 injections, daily at first, then once per week then once per month for the rest of one's life.  I'm told that just some but not all of those with PA respond to 3,000 ug doses of oral Methylcobalamin tablets.  Note that the US Recommanded Daily Allowance is just 2.4 ug.
So far I've had just a blood test for Methylmalonic Acid, which will be high if B12 is low.  My own interpretation is that this test was inconclusive - I still await my Neurologist's interpretation - but there are six or eight other tests, the most-definitive being a bone marrow biopsy which would reveal any inability of the marrow to produce red blood cells.

thread_title:  Broca's Aphasia Caused By Vitamin B12 Aphasia? 

message: I don't understand why there is a section on Mirror Neurons in this article. Nothing in that section says anything about Broca's area. Also, it seems especially inappropriate given that its under the main section titled "Functions" which is supposed to be about the functions of Broca's area.  I'll concede that given our very tentative understanding of the brain and language you could make a case that Mirror Neurons are important to language and hence Broca's area but no more or less than many other concepts (e.g, the theory from Lakoff and others that somatosensory processing is essential to language, or the recent work that Chomsky talks about in his book with Berwick where he identifies pathways that are hypothesized to support recursion). Can someone justify why we need to mention Mirror Neurons in this article and if so edit that section so the relevance is clear? If not I think that section should be deleted and will do so after a while if no one comes up with a justification. --MadScientistX11 (talk) 22:24, 8 April 2019 (UTC)
replies: text: I'm removing the Mirror Neuron section. For one thing, that section was speculation anyway. There is no strong evidence that mirror neurons play a significant role in human language. But more importantly that section said nothing about Broca's area which is what this article is about. Here is the text that I removed:
===Mirror neurons===
Communication, both verbal and nonverbal, requires that the interacting individuals stay "tuned" to one another. Mirror neurons were discovered in the 1990s in frontal area F5 of the monkey cortex. These neurons are active during execution of object-related hand actions, but they are also active, importantly, when the monkey is just observing similar acts. For example, the mirror neurons are activated when the monkey takes a raisin from a tray and also when he views another monkey or the human experimenter doing the same. No information is yet available about possible hemispheric lateralization of the monkey mirror neurons.
Mirror neurons have visuomotor properties, being sensitive to goal-related motor acts, but they can also be activated by sounds that imply actions. Importantly, the mirror neurons do not only react to visual input and then project, via some transformational step, to motor-output-related neurons but are also part of a system that forms a neuronal representation of the observed motor acts. Similar to F5, the rostral part of the inferior parietal cortex contains neurons that are active during action observation and execution; this region receives input from the STS, which is known to contain neurons responding to biological motion.
