> 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 - “this technique that changed the subject’s brain waves sufficient to literally impact their sense of self - but don’t worry! It’s non-invasive!”

“...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]”
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?
i guess putting your head in a microwave would also be considered "non-invasive" according to this logic. makes sense!
