Talk:Papez circuit

message: The statement "...the Papez circuit (pronunciation IPA: ˌpeɪ.'pɛz[1]) of the brain is one of the major pathways of the limbic system and is chiefly involved in the cortical control of emotion." needs to be modified or deleted.  The belief that the Papez circuit is involved in emotion is a historical footnote (worth mentioning but now known to be untrue).  The Papez circuit is now known to be involved entirely in the induction of long-term memory.  Indeed, all of the structures shown in the figure are related to memory, not to emotion.  Moreover, the pronunciation cited is incorrect.  It is pronounced "Papz" (1 syllable, long a).  Does someone have time to make these corrections.  If not, I will try to do it this summer but, ironically, right now I need to prepare a lecture on the limbic system.   —Preceding unsigned comment added by 129.137.220.9 (talk) 12:56, 13 May 2010 (UTC)
thread_title: Corrections?

message: I believe the recent changes give undue weight to the contributions of Christfried Jakob.  I asked the editor who made these changes to revise them, and got no response.  I then reverted the changes, and then several days later the same editor (presumably), unregistered and working from a different ip address, undid the revert.  It seems necessary to have administrative action here to avoid a revert war.
Let me review the situation.  "Papez circuit" has been standard terminology in neuroscience for decades.  The phrase originated in a famous review article written by James Papez in the 1930s ("A proposed mechanism of emotion", JW Papez, Arch Neurol Psychiatry, 1937, 38:725-743).  Earlier this year, LC Triarhou published an article arguing that many of the points that Papez made were anticipated by Christfried Jakob near the beginning of the 20th century (Neurosci Biobehav Rev. 2008;32:984-1000).  The article is scholarly and usable for Wikepedia, but even so, this single article does not justify a complete rewrite of the Papez Circuit article that gives all the credit to Jakob and disparages the contribution of Papez.  As I suggested to the editor who made these changes, I believe it would be acceptable to add a paragraph to the original text to state Triarhou's ideas, but the present version goes way overboard. So here we are.

replies: text: The same IP made the same change to the Papez circuit template. I have reverted this. Perhaps that template should be reverted, too --Crusio (talk) 09:02, 28 July 2008 (UTC)
thread_title: Recent changes

message: An IP editor today changed this article to state that the Papez circuit is involved in the sense of direction rather than in emotion; the edit was reverted by Crusio as unsourced.  The edit actually gets at an important truth:  there is very little real evidence that the Papez circuit structures are involved in emotion.  In rats at least, several of these structures have turned out to contain head direction cells; see that article for pointers to the evidence.  It would be appropriate for the current article to deal with this—but Crusio is correct that a sketchy unsourced statement is not the right way to do it.

replies: text: Not to mention the long-known place cells. Nobody denies that the hippocampus is, in some way or another, involved in place learning. But then again, nobody denies the amygdala is involved in fear. A lot of the structures constituting the Papez circuit have not really much to do with orientation, though, so although it is correct to state that some parts of the circuit are involved in orientation, I don't think it is correct to say this about the whole circuit. As an aside, the Papez circuit is not really mentioned much any more in current neuroscience research. --Crusio (talk) 08:08, 12 September 2008 (UTC)
replies: text: The connection is stronger than that makes it seem:  HD cells have now been found in the mamillary nuclei, anterior thalamus, retrosplenial cortex, parahippocampal cortex, and (rarely) hippocampus -- which is pretty much the entire Papez circuit except the anterior cingulate (which hasn't been examined).  Many of us think that this must be more than a coincidence:  see for example . Looie496 (talk) 16:51, 12 September 2008 (UTC)
thread_title:  Sense of Direction 

message: IP editor, I agree with you that that's the correct pronunciation -- at least, I was taught the same thing.  But it is completely useless to add it in a broken format with your professor as source.  Therefore for the moment I've simply removed the pronunciation.  If we can find some verifiable source that says this, and if it can be formatted correctly, I have no problem with that pronunciation going into the article.
