I bought the first commercially available Trans-cranial Direct Current Stimulation (tDCS) device from foc.us.  This particular headset stimulates the pre-frontal cortex which controls information processing. 

Studies have shown that the effects of tDCS are permanent, so I'm pretty excited about it. 

 

You can grab one for $249. Euro/Pound as well

I haven't seen anything about permenant but long lasting and cumulative have been mentioned. What are your plans with it? are you trained in it's use or know where you are targeting? or just doing a little bit of mad science self experimentation? :D

Yea just a bit of experimentation! I'm not trained in it but I'll definitely do some more research before it arrives. And for this particular headset, the cathodes and anodes are fixed on the pre-frontal cortex unfortunately ( I would love to experiment with different sections of the brain). I'm thinking about tracking my cognitive progress (if any) with some homemade or online tests. It ships in July so I'll let you guys know how things go. ;)

This is equal parts cool and hilarious.

Agree completely with cool, not sure what you mean by hilarious.

I might tinker with some of this at some point, but my results may vary as I am not neurotypical and every indication seems to suggest that what is actually happening in these is inducing a mild autistic like hyperfocus or in some ways a hypnotic style focus.

 

I'm also warry because I've known more than a few people who bought into quack science about introducing magic electricity in the same way that snake oil sales people looked for. Look up the Zapper. You'll see all these people talking about improving the immune system and resolving sickness and disease via running current through their body. A lot of people have bought into this sort of thing, and they enthusiastically want others to discover the wonders of this. There is so much techno babble that from the tech side makes sense but relies of uneducated thought processes with regards to immunology and medical science. http://www.quackwatc...ncer/clark.html

 

And while Transcranial is not the same thing and has been used and tested for legitimate effects by legitimate scientists in the feilds to which they are applied, I still have a very strong suspiscion of magical energy treatments and such. I do think as a retraining tool it could be potentially useful as it could help retrain pathways, much like having somebody guide you through an action until you've experienced it enough that you can instinctively do it. But it would depend of wether or not the effects of the device are infact neurological or in part psychological.

 

I also have to wonder about the idea that if it's able to change brain function I would expect there to be more risk and potential long term changes. If for instance it pumps up the brains natural supply of opiates does that mean with chronic use the natural opiates trigger system will register higher levels and start to amp down natural release, forcing a dependance? Does this apply to other things as well? Could you actually cause neurological decline by over stimulation and then desensatizing and dependance? If that can't happen then it increases my suspicion that it has little real lasting effect on the brain.

 

But in the end I just don't know enough.

I did read somewhere that if you use anodal stimulation on an area near the primary motor cortex, that it releases endogenous opioids. So if stimulating that area for extended periods of time, you could probably gain a dependence to it or get depressed when it discontinues its natural release.

 

If you go on reddit, there is a subreddit called /r/tdcs. Its basically a forum about with a bunch of articles and personal observations with tDCS.

okay I keep seeing mention of increases in white matter of the brain and instantly my mind says isn't that the part that deteriorates and is not regenerating fast enough in cases of MS? Is this a potential therapy vector for MS? or would the lack of white matter and failing regeneration cause hazards for MS trying this? for that matter does tinkering with our white matter make us vulnerable to MS?
