Is there any data about the tendency towards of beta rhythms vs not in different cultures around the world?
Since brainwaves are associated with brain disorders and brain disorders are associated with genetics, it would be worth (albeit dangerous politically?) to investigate the link between brainwaves (and by extension, different cognitive faculties) and ethnicity.
I wonder how much this can be applied to day to day life. For example, the Binaural app on the iOS app store acts as a wave generator that lets you listen to specific frequencies. I'd be interested to see if you could force yourself into getting beta wave activity in the brain by just listening to beta frequencies -- almost as if to tune yourself manually.
Why would they use a different order of magnitude. Surely they know that there are billions of them (100 bil in fact).
Earlier quoted context omitted.
I can’t tell from this, but does this demonstrate a causal link or is the headline somewhat disconnected from the paper? That is to say, does the brain truly rely on beta rhythms, or are they just a symptom of something else?
I think the answer is necessarily "no," because the rhythm is a sign we observe of some functional system in the brain, not the functional system itself. Similar to how your heart rate is just a sign of the beating of your heart, only the latter of which is a real functional mechanism. Something is happening in the brain that generates these patterns and which also has to do with the cognitive faculties described in…

Makes one wonder about the effects of raves.
It seems almost definitional that this effect is correlative and not causative unless the authors are positing that there are structures in the brain whose purpose is to generate brain waves or that we just massively misunderstand the function of neurons. I read the previous paper summary linked to and I didn't see a way these waves are supposed to affect the neurons. Is there absolutely any theory as to the mechanis…
My understanding of neuroscience is limited however. Can someone with a better understanding point me at what I’m missing?

It's unclear whether local field potentials (LFPs), of which "beta rhythms" are one specific frequency band (approximately 12-30hz), are actually a mechanism that the brain uses to transmit information. Information is known to be transmitted via the discharges of single neurons; LFPs represent the aggregate activity of tens of thousands of neurons within ~3mm of a recording electrode. It's possible that these aggregate voltage fluctuations feed back onto the activity of single neurons [0], but LFPs are generally considered an emergent property of populations of neurons as opposed to an information transmission mechanism in their own right.

I would love to see someone reply with personal experience. I have tried similiar apps for extremely brief periods and could feel a change.
