I really recommend Transcranial Magnetic Stimulation: A Neurochronometrics of Mind (A Bradford Book) by Vincent Walsh for anyone who wants a really concise view of one aspect of the field. I was super interested in this when I was in my first few years of college but the fear of electrocution pretty much dissuaded me from trying anything like building an apparatus myself.

Isn't there a commercial device built with safety mechanisms to do this?

There is not, as it would have to go through medical device approval.

In your profile, enable showdead. The history goes back a way. Seeing all those unaddressed, never-seen comments causes me some personal existential self-examining on the value (or rather, potential non-value) of my own thoughts :)

So why can I see his comment then? if he's shadowbanned? because you commented?

Because I vouched for it

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..

Not sure about this article, but there is some work using ultrasonic transducers that I don’t see mentioned frequently. (Magnetic stimulation has a longer history.)

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

There are already treatments like this. When I was in high school I started a minor computer repair business. One of my customers was a treatment service where they would place electrodes on the head of an individual to measure certain brainwave activity. The electrodes were connected through a device back to a laptop which was playing a video. I'm explaining it very imprecisely (I'm an expert by no means) but the wa…

There are certainly criticisms, grains of salt, and hucksterism involved, but I think it would be premature to entirely dismiss neurofeedback. Importantly, there is not “one kind” of neurofeedback, and the specific EEG patterns to optimize for is open to debate.

Douglas Dailey has some interesting hypotheses and an excellent list of references for further investigation: https://tagsync.com/

Neurofeedback isn't quite the same thing as neuro-stimulation. Neurofeedback just encourages (through positive feedback) the brain to stimulate itself :)

I've been practicing meditation for a few years and it has slowly but steadily improved my ability to concentrate. (Also worth mentioning that witnessing emotions as a field of sensation allows them to "dissolve" instead of getting stuck, and has helped me overcome various addictions and roadblocks.)

Meditation was shown to develop the prefrontal cortex (involved in decision-making, working memory, inhibition, emotional regulation..), which is (are) underdeveloped in people with ADHD.

I'm wondering how this kind of independent, willpower based practice compares with the constant external feedback of neurofeedback training, seeing as one of the main deficits in ADHD is self-motivation. My guess is that a combination might be most effective: train the concentrated state itself to make it more accessible, and then train the will (habit) to access it.

Or put another way, make use of both internal and external technology :)

Amen. HN hates any taboo thought crimes.

Thinking is fine, speaking can be problematic. And if you believe speech can do no harm, it can not possibly do good, either. Or we could just randomly generate text and improve the world.

I'm struggling to remember the name, but there was a company that sold a TDCS machine marketed as a game performance enhancement device. It only did one montage and was ridiculously unsafe. It used to leave red marks under the sponges on my forehead. Eventually, the app that controlled it aged out of the app store.

You have a long list of good comments, so it's worth telling you that you were shadow banned at least 6 months ago... I just vouched for this comment and I have showdead enabled.

fao_ -- Thanks a lot for that gesture! Very kind. I did not realize I was shadow banned at all and I'm not sure why I would have been. It does sum up "the internet" in 2019 perfectly for me though.
