Should this article be named pulvinar, pulvinar nucleus, or pulvinar nuclei? It seems that the pulvinar part of the thalamus is usually called the pulvinar nucleus, but it is also divided into 4 named subnuclei. It just seems strange to only call it the pulvinar without nucleus in the title. Cmcnicoll (talk) 03:26, 18 April 2010 (UTC)
I'm not sure. Per MEDMOS, we try to align anatomical terms with Terminologia Anatomica unless there's a good reason to override it. A list of the TA terms for the diencephalon is available here. If you scroll down to "A14.1.08.104", the pulvinar itself does not have the term "nuclei" in it. At "A14.1.08.610", we have "nuclei pulvinares", but it is conceivable that there are portions of the pulvinar which are not nuclei (analogous to the White matter of the Arbor vitae.) MeSH and NeuroNames follow a similar convention. But it's a close call, and I wouldn't object if it were moved. --Arcadian (talk) 03:41, 18 April 2010 (UTC)
Yeah, I agree this might be considered splitting hairs. I looked up the entry in Stedman's, which was pulvinar, and it said that the TA term is pulvinar nuclei (nuclei pulvinares), as you noted. I then found the TA in google books, and it looks like the source of confusion is the difference in what we are describing. Pulvinar thalami (A14.1.08.104), aka Pulvinar, is an external feature of the diencephalon. Pulvinar nuclei (A14.1.08.610) refers to the internal feature of the diencephalon. So the answer to the question depends on what the article is written about. I think that the article is mainly about the nuclei, and should be moved to Pulvinar nuclei. The intro could read something like "The pulvinar nuclei (nuclei pulvinares) are a collection of nuclei located in the pulvinar thalamus. The pulvinar part is the most posterior region of the thalamus." Cmcnicoll (talk) 04:52, 18 April 2010 (UTC)
