has anyone built any diy projects for this yet?
Have you checked how many Volts are needed to send this high frequency current through the brain?
It depends on the electrode impedance but somewhere in the neighborhood of 2V.

Re: Noninvasive theta-burst stimulation enhances skill learning
#32On HN the use of psychedelic microdosing for problem solving/creativity is usually the only context that is being discussed. But there are others. For rapid motor skill improvement I suggest microdosing LSD or shrooms and then doing the resp. excercise/practice. Ideally with a teacher/master present, to correct/help. Also applying the techniques from the famous "The Inner Game of Tennis" book during the trip window h…
I had some friends/peers go through a period of micro dosing. They had similar beliefs about increased learning based on similar theories of neuroplasticity, fueled by trendy podcasters and influencers. As an outside observer, I got to a point where I could usually tell which days they were microdosing. The biggest tell was that their self confidence went up significantly. They would consider routine accomplishments…
One of the keys of being able to learn something adroitly is believing that you are capable of learning it, and one of the pitfalls is believing you can do something that you cannot.
Some doubt is good and healthy. When doubt is preventing you from living a good life then some temporary chemical bypassing can be good, but if there is no doubt in your way then you're just chasing the high.

#33Interest idea. I wonder if somebody there working on such thing, or want to collaborate.

Just wondering, if you take a wide beam approach to stimulating the brain with electricity, doesn't that sort of just reamplify whatever is going on in the circuitry and/or activate whatever's already latently there? How's this any better than a line of coke or six cups of coffee?
Yes to your first question, or at least that's where most literature leans. In brain stimulation research the terms online and offline refer to whether stim is delivered concurrently with a task (online) or before/after a task (offline). Generally greater benefits are seen in studies that repeatedly pair brain stim concurrently with a task over several sessions, but of course many methodological factors (intensity, d…
I would (slightly) disagree with that.
The hope is often to enhance whatever's already going on in the brain--and this is a sensible goal because there's often less neural synchrony in some diseases (e.g, schizophrenia) or situations (e.g., memory lapses).
However, the brain has its own internal dynamics--and they're complicated! You can 't just blithely write a new thing on top of them and expect it to work. In our experiments, doing so often backfires: stimulating at 5 Hz often makes makes cells already firing at 5 Hz act less rhythmically, not more. The reason is that the brain's oscillations drift in frequency and abruptly reset, so they "compete" with the imposed oscillation. This is a pretty well-studied phenomeon in other contexts (e.g., sloshing in rocket fuel tanks or nearby pipes cancelling each other in organs).
TI is exciting because you could potentially sense what's going on and adjust the stimulation accordingly, but we've got a lot of work to go.
