:Looks good. Maybe put in a bit on the role of dopamine in the basal ganglia. We're always glad to have another person with neuroscience interests on board. Sayeth 06:00, Nov 20, 2004 (UTC)
I've updated the page a little.  In particular, there is a growing
consensus that the basal ganglia has many more roles than just
movement related, and I thought that should be expressed. Also added a
bit on its history (lots more could be done there).  I am planning to
add some digital pictures of the anatomy soon, I think that should
make anatomically locating them clearer.  Comments/complaints welcome.

replies: text: Yes. In fact there are many more connections than are shown in the diagram. The diagram is of the classic model of basal ganglia function, as proposed by Albin, Young and Penney (TINS 1989 vol 12:366–375). This model used a simplification of the anatomy of the basal ganglia in order to propose the mechanisms underlying both the normal function of the basal ganglia and the changes that occur in diseases such as Parkinson's disease and Huntington's disease. An anatomically correct diagram would not only have a STR->SNc connection, it would also need (amongst others) cortex->STN; STN->GPe; GPe->GPi; GPe->SNr; SNc->STN; and SNc->GPe.

:Technically you are correct - there are not supposed to be ganglia in the CNS. But the terms are used interchangeably, and frankly I've heard "basal ganglia" more often than "basal nuclei". JFW | T@lk 13:10, 31 October 2005 (UTC)
replies: text: *JFW is right. Although there is a small group of people (myself included) who prefer the term "basal nuclei", almost no one in neuroscience refers to them as such. Technically the ganglia of the mesencephalic nucleus of V are located within the CNS, but that is an exception to the rule. semiconscious (talk · home) 21:21, 31 October 2005 (UTC)

message: JeremyA systematically changes my corrections for reintroducing an old fashionned conception. An encyclopedia must present things as they are known not as they should be preached.
:I think the problem is not with your views, I think the main problem is with the style of editing. By all means correct any factual errors, or update the articles as you see fit, however keep in mind that you are not talking to a scientific audience, so you have to be very careful to use clear wording, define any terms, and link these terms to other WP articles. Check out WP:Style for further guidelines. Thanks for your contributions. Nrets 18:36, 8 May 2006 (UTC)
thread_title:  Complain 

message: I have moved most of the new content into a new article, Anatomical subdivisions and connections of the basal ganglia, and reverted the rest of the article to this version from April 18th. It is great to get so much new content, but because many of the new editors on this are unfamiliar with how to format, outline, and cite Wikipedia articles, we have to get the main article back to a stable state before we can move forward. I ask the anonymous editors to read Wikipedia:Why create an account?, and to anyone adding controversial material, I ask you to read Wikipedia:Citing sources. --Arcadian 14:08, 16 May 2006 (UTC)
replies: text: Whoa there, nothing was erased it was just moved to here. The way you had written the page had made it basically unreadable. While the information is good, it was incredibly disorganized, written completely with disregard to the manual of style, unreferenced, and full of gramatical and spelling errors. If you want a good example of a neuroanatomy article on Wikipedia, look at cerebellum which was the work of many people's painstaking efforts to trim the information to the most essential bits, in a clear, organized manner.

thread_title: Reversion

message: Im a med student, and in lectures, the basal ganglia's constituents were grouped differently to the way they are grouped in the article. Is this article correct? I was told that the basal ganglia contained five constituents - the caudate nucleus, the lentiform nucleus (globus pallidus and putamen), the substantia nigra, the subthalamic nucleus and the thalamus. The caudate nucleus and the lentiform nucleus were grouped together under the name corpus striatum, the caudate nucleus and the putamen were grouped as the striatum and the striatum and nucleus accumbens were grouped as the neostriatum.

replies: text: Gerard, I want to thank you for all of your enthusiasm and hard work on Basal ganglia and Thalamus. However, I do want to encourage you to read Wikipedia:No original research and Wikipedia:Verifiability, if you haven't already. --Arcadian 17:48, 18 May 2006 (UTC)

text: Hi Gerard, "user" Arcadian refers to that wikipedia policy that - ideally - or according to the rules of "good encyclopedia sciences", the wikipedia should be a bit "boring" in that the info it contains, should be extracted from multiple articles that talk about / bring insights from research="original knowledge" together, enfin - that the knowledge is not under discussion anymore, that there is consensus. So, yes the wikipedia like any encyclopedia will always be behind on the original research insights.  But for you there's an easy workaround I think because you can always state: this is not my personal interpretation or from my own fundamental research that nobody else has ever reproduced, no this is knowledge extracted from a compendium from the "International Basal Ganglia Society" - that is where are all the nerds on the topic meet, exchange and one of the things we take up in our publications are the conclusions on the new insights gathered from "original research" done by our members. Right? PS I could find all the publications and conferences of the International Basal Ganglia Society but you/it doesn't have a website itself? Thy and all your colleagues, researchers for your work. :), SvenAERTS (talk) 08:40, 26 May 2022 (UTC)

thread_title: Please

message: These two articles need to be wikified. 
* Anatomical subdivisions and connections of the basal ganglia
*Primate basal ganglia system
From the history of the discussion, i understand that these enw pages were created in order to manage the new inputs from other wiki users. Being an encyclopaedia i suggest that these articles be merged back to the main article with appropriate wikification Kpmiyapuram (talk) 18:30, 4 April 2008 (UTC)
replies: text: I think Primate basal ganglia system should be kept. There is too much primate-specific information on the page to merge into a page which should cover amniotes and amphibians, sub-pages like this are more common for primates (see Evolution of color vision in primates and Sexual dimorphism in non-human primates) as there is a lot of research available. Jack (talk) 22:55, 17 June 2008 (UTC)
replies: text: I've removed the merge template for now as no consensus was reached. I think trying to merge that 71 kb behemoth would prove difficult and is unnecessary. Cheers, Jack (talk) 01:18, 13 August 2008 (UTC)

text:  It is probably worth to have a discussion on content that could be merged. A lot of information would be unreachable as nobody would search specifically for primate basal ganglia system. As mentioned in the discussion page of that article, the more specialised articles should reflect on the differences or deviations from the main article. The main article could be Basal ganglia as the generic name suggests. Kpmiyapuram (talk) 17:31, 15 December 2008 (UTC)

thread_title:  New pages on same topic 

message: I've raised the importance rating for this article to Top, and dropped the quality rating to C, although I actually think Start might be more appropriate.  The importance of the basal ganglia in modern behavioral neuroscience is huge, and this article hardly begins to capture the reasons why it is so important. (It should really be Top importance for neurology as well, but I don't belong to that project so I'm not going to make changes for them.) Looie496 (talk) 03:37, 22 September 2008 (UTC)

replies: text: If you're talking about the image at the top, the biggest problem is that it's a GIF image, and scaling of GIFs is badly broken right now.  Things would be better if the image were replaced by a PNG, or even better SVG, version, or better yet, a different image that uses the available space better.  I don't think the enlarging the infobox would be a good solution. Looie496 (talk) 17:16, 19 February 2009 (UTC)

text: O hai guyz, I was wondering if, since we're talking about images, can someone post one with a little more detail on the connections and interactions between specific cortices and the striatum?  I'm specifically looking for the bits about motor function.  Cheers in advance if you can find something.Tarkaan (talk) 04:18, 18 September 2009 (UTC)

thread_title:  BIPOLAR DISORDER 

message: I had a stroke.  Meaning, the vehicle drove into my car (driver-side, front.)  My left-aorta (lap seat belt) is where the blood clot was.  It took three month in order to get to my left brain.  
Now, the surgeon brain saw my basal ganglia fill with blood.  
I know enough to comment on Broca's Area, system motor, etc.
But, couldn't there be a question as to my basal ganglia over-riding my "aphasia"?
Thank you.

:Thanks for asking this.

message: There used to be an image of the circuitry posited by the parallel pathways model (which is still up) side by side with an image so many of the anatomical connections that we now know exist and are in tension if not contraction with the pp model (i.e. Yelnik 2002).
