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)[reply]

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)[reply]

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.

Looie496's current (nov 2008) rewrites

Although rewriting the page to improve clarity is useful, the opening section of the page has been completely stripped of references and wikilinks. Do you (Looie496) intend to add that stuff back in or should someone else? The wikilinks fix is quick, but finding the appropriate references to support those statements might take a while. I assume you must know appropriate papers to be making the claims (I'm not saying the claims appear wrong, except one that I'm not familiar with, just that the references are important). digfarenough (talk) 22:17, 29 November 2008 (UTC)[reply]

Vague to the point of vapidity?

I came to this wikipedia entry from the ADHD article, where it stated brain studies showed a high theta wave presence in persons with attention-deficit/hyperactivity disorder...

Surprise!? I can't find out what that means: this Theta wave article states: "the presence of theta correlates with performance in several learning tasks."

correlates up = good? correlates down = not so good?

I guess I can't blame somebody for not informing my ignorance. I'm bringing nothing to the table but my lack of knowledge...

Similarly the statements about theta potentiates processes related to long-term/physical memory...what? We're talking ADHD...these (us) folks are memory and performance champs? Then step aside world and crown me king!

So please, informed persons, let's get these points clarified? thanks, B. Bumble —Preceding unsigned comment added by 192.251.94.253 (talk) 15:17, 9 March 2009 (UTC)[reply]

I clarified the sentence. However those statements are really referring to experiments involving rats, and might not apply to theta in humans. You can look at the "Terminology" section for an explanation of the issues that make it really difficult to write this article in a straightforward way. Any suggestions would be welcome.

section on meditation

This appears to be far too vague, especially considering the large number of poor quality claims in the area made without adequate controls. For instance, “Ospina et al. (2007) meta-analyzed a large sample of studies within five broad categories of meditation practices (mantra meditation, mindfulness meditation, Yoga, Tai Chi, and Qi Gong). Reporting poor methodological quality in the studies examined, they suggested that positive therapeutic effects and well-being may not be specific to the meditation practices and can be achieved by somatic relaxation training and prayer.”^[1] Parzivalamfortas 06:55, 19 October 2018 (UTC) — Preceding unsigned comment added by Parzivalamfortas (talk • contribs)
