Talk:Theta rhythm

From Wikipedia, the free encyclopedia

[edit] claim in article

The origins and functional significance of theta rhythms in both humans and other animals remain unclear.

As I can recall, there has been some advance about this. Now no time to write to the article, but... http://www.google.hu/search?q=tamas+freund+theta+(wave+OR+rhythm+OR+oscillation) Torzsmokus 02:33, 3 June 2007 (UTC)

I added a title to this comment. I'm not sure where that claim in the article came from, but I suppose it is right to question it. I'm not sure what "origins" means. The circuitry that produces theta in both cortex and in hippocampus is pretty well traced out, to my knowledge. If they mean the evolutionary origin, that I don't know anything about. The article does feature one possible functional role though (that I added quite a while back), so I think this sentence needs to be changed or removed. It is strictly true, though, that the functional significant is not unambiguously known, though there are suggestions, like Freund that you mentioned. Buzsaki surely has ideas, and Neil Burgess's grid cell model that we (the lab I work in) recently found experimental evidence in support of also suggests an important function of the theta rhythm. So there are a lot of theories that have experimental support, but in my mind it still isn't perfectly clear what theta rhythm is doing. I think I'll remove that claim in the article, though. digfarenough (talk) 21:46, 3 June 2007 (UTC)

[edit] Noteworthy: "spacial" and "spatial"

This article refers to both spacial and spatial awareness, both terms are correct as used but not quite interchangeable. The common use term is "spatial", but the conference on Global Change in Moscow in 1988, qualified "spatial" as a 2-dimensional reference and "spacial" as a 3-dimensional reference.
