Wow, that’s really interesting! It seems like alpha waves are the ‘tick rate’ of this system, and some set number of ticks are required to update the body model?
It's waves all the way down!

Re: Scientists identify brain waves that define the limits of 'you'
#22The idea of "ownership of a body" made me think about a quote I heard a long time ago, while talking amongst musicians while waiting to get up and perform. It felt like some secret knowledge that I gained privilege to, while somewhat inebriated and it hasn't left me since. > I _have_ a body, I _am_ a soul. Maybe what they're identifying is the first half of that statement, how we interpret the former, through the pre…
Dualism is almost always unhelpful as a model. Your soul is a process your body runs, they are indistinguishable.

#23FTA: > With a third group of participants, they used a non-invasive technique called transcranial alternating current stimulation to speed up or slow down the frequency of a person's alpha waves. And sure enough, this seemed to correlate with how real a fake hand felt. I know this is largely orthogonal to the article, and I know what “non-invasive” means and why it’s used in this sentence, but it made me chuckle - “t…
“...it's not out of the question that you might have a very minor case of serious brain damage. But don't be alarmed all right...[it’s non-invasive]”

#24So, how far does the human electric field extend outside the body? May be only picovolts or in that range... But can we measure that? Does the field exist past our skin? Can things like meditation modify that? Or how about stuff like OOBE's like what some folks call astral projection? What do those practices to to the body's electric field?
There is something like the heart field, about 3 to 4 feet according to the article.

Meditation can alter a lot of “you” , and there is a reason you learn the advanced stuff under a guru (yoga mostly) or monk (buddhism).

#25I do wonder how far they would get with the phantom limb stuff. We know phantom limb stuff is encoded before birth so would alpha waves adjust something so fundamential?

I don’t think the study claims alpha waves are literally the body model’s clock. What they show is that the speed of alpha cycles influences how precisely the brain binds sensory signals to generate the feeling of body ownership.

#27Wasn’t this phenomenon already described by VS Ramachandran in his book Phantoms in the Brain?

#28Interesting.
Now run the same kinds of tests while listening to music, meditation, sleep, orgasm, psychoactive substances (including caffeine/alcohol/nicotine), during simulated stress event (hard slap in the face?), on different age groups, genders, races. Perhaps there are more than one version or definition of "You" that arises in certain circumstances.

Nah.

Maybe.
