#13The 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 presence of the latter.

#14FTA: > 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…
i guess putting your head in a microwave would also be considered "non-invasive" according to this logic. makes sense!

You can do that with mental phenomenon too - eg, having memories, feelings, consciousness, thoughts. All aspects of "I" that might be present or not - so they can't really be said to be you as much as possessed by you for a moment. Insofar as a soul exists for you to be ... it is quite small.

#16So, 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?

#17So maybe tin foil hats can be useful after all?

#18The manipulation part is what fascinates me. They didn't just correlate alpha wave frequency with ownership perception. They used transcranial stimulation to artificially speed up or slow down the waves, and the subjective experience changed accordingly. That's a pretty direct causal link between a measurable brain state and something as fundamental as "where does my body end?"

If invasive means using surgical tools to open up the skin and organs, then non-invasive means all things that don't require surgical tools.
OTH nearly all brain experiments are non-invasive. Did they mean to use the word to downplay how seriously impacting the experiment was?

Nah, in the context of weaponry it is called "less than lethal".
