Huh, I wonder if there is something similar to be studied with autistic brains.

(My step-daughter has HFA; difficulty with working memory and executive functioning is common for HFA females).

Say wooot?

Since I can't read the paywalled article I'm wondering how exactly do you apply "noninvasive stimulation" on these frequencies. Was it audio, electrodes on a shaved head, combination of drugs, did this work in rats first etc..

I don't think we can call electrodes on (in?) a shaved head 'non-invasive'...

So they're applying stimulation with electrodes placed on the head. tMS and stuff like this are the main ways available right now for non-invasively inducing oscillatory activity.

I was wondering if something like this might help with my ADHD... a thinking cap, if you will :)

it is 'on'. And so, yes, we can:
