Talk:Nucleus accumbens

Core vs. Shell differences
I think it would be good if we detailed the differences in the core vs. the shell. Granted, the differences are usually pretty subtle, but since there's mention of it in the beginning, I think it's important we work on it. I have a really good review (32 pages of review) that would probably be a good starting place, but I'd like some help on this if possible. Maybe we could first look at the role of the shell vs core in addiction, as the shell experiences much higher levels of dopamine increase in response to addictive drugs, and is much more closely linked to rewarding effects of addictive drugs.

If anyone wants to look over the review as well, it's Nucleus accumbens shell and core dopamine: differential role in behavior and addiction by G. Chiara, Behavioral Brain Research. 2002.

Sentence fix
This sentence has no predicate:


 * The nucleus accumbens, striatum, and basal forebrain together for the ventral striatum. Rintrah 03:54, 17 July 2005 (UTC)
 * Thanks. This sentence is accurate, just poorly worded. It is now fixed. Semiconscious  ( talk  · home) 04:20, 17 July 2005 (UTC)

Description of the Location of the Nucleus accumbens
I need a better one or just mark the area in the current picture thanks

 * There's a good diagram here, a more detailed but less clear diagram here, and links to many more illustrations here. I've also added a second diagram, but it's very rough, and a little misleading, so if I were you I'd place greater faith in the links above. --Arcadian 01:28, 24 March 2006 (UTC)

Olds and Milner
I have just read the Olds and Milner study and although it does indicate that rats did repeatedly press a lever to stimulate part of its brain, it neither mentions the nucleus accumbens, nor does it say anything about the rats preferring the stimulation over food and water.

Here is the link to the article.

Perhaps there were other studies done by the same two researchers? —The preceding unsigned comment was added by 66.108.18.176 (talk) 16:39, 19 February 2007 (UTC).

Role in Addiction (possible factual error)
Under the "Input" section (http://en.wikipedia.org/wiki/Nucleus_accumbens#Input), shouldn't the last sentence be "...almost every addictive drug has been shown to increase dopamine levels in the nucleus accumbens," instead of "...almost every recreational drug..."?

I'm not sure, which is why I did not change anything. (User maas15:maas15) —Preceding unsigned comment added by Maas15 (talk • contribs) 00:53, 21 January 2010 (UTC)

Inappropriate content
I'm new to this, but the sentence

`It is thought that the NAC plays a central role in Michael Meagher's unusual affinty for the male anus (whence comes his pseudonym: the butt-pirate). '

would appear to be inappropriate. Jon g hall (talk) 08:36, 2 November 2010 (UTC)

Merge proposal
We currently have separate but short articles on the shell and core of this structure - it seems to me appropriate to merge the information into this page, since the two elements, though distinct from one another, are inexorably part of the Nucleus accumbens. I'd also support selectively merging information into this page to create a "Structure" section, with links to the two merge candidates, as an alternative to a full merge-and-redirect.

 * Hi Yunshui 雲  Sounds like a good idea to merge both of these small articles into this one!   Lova Falk     talk   07:23, 24 June 2013 (UTC)
 * Support needed merge Iztwoz (talk) 18:09, 2 April 2014 (UTC)
 * Support. Currently quite confusing. --LT910001 (talk) 00:31, 3 April 2014 (UTC)

Recommendation that certain additional material be added
Just saw Guardian Web page "Brain's music pleasure zone identified", re article in Science, re finding that "the most popular songs elicit the strongest response in the nucleus accumbens," which might be appropriate to include in "Research" section of the Wikipedia article (particularly since latest addition was in 2010). — Preceding unsigned comment added by 4.154.230.12 (talk • contribs) 02:08, 7 May 2013‎
 * The article also warns that Salimpoor's results should not be over-interpreted and "Reward was only a snapshot of one particular brain system and its involvement in music, Scott said. "But don't think it's telling you everything about the totality of how your brain engages with music." So I don't think it is a kind of information that should be included in this article.

NAcc core and Slow-wave sleep
This review mentioned this function of the NAcc core, citing these two studies. Worth covering, although it would probably be a good idea to find another review which covers this in more detail than a passing mention.  Seppi  333  (Insert 2¢) 01:16, 18 January 2018 (UTC)


 * A paywalled review exists, with an abstract that suggests relevance. Petergstrom (talk) 17:18, 18 January 2018 (UTC)
 * Thanks for the link. The full text of that review can be accessed (technically pirated, arrr matey) via sci-hub using .  Seppi  333  (Insert 2¢) 05:05, 20 January 2018 (UTC)


 * Here's a recent (December 2017) "Research highlight" article published in a Nature Publishing Group journal; while it's not technically a review, it is a secondary source for the following primary source.

I'm not sure if it's worth transcluding this section from caffeine into the part of this article where the effect on slow-wave sleep is covered, but I suppose that can be decided after something about sleep is added.
