Is DIY Brainhacking Safe? 183

An anonymous reader writes "My colleague at IEEE Spectrum, Eliza Strickland, looked at the home transcranial direct current stimulation (tDCS) movement. People looking to boost creativity, or cure depression, are attaching electrodes to their heads using either DIT equipment or rigs from vendors like Foc.us. Advocates believe experimenting with the tech is safe, but a neuroscientist worries about removing the tech from lab safeguards..."

      I'm thinking not long. Although tempting, I don't want to be the guinea pig.

      I learned how to fix and improve computers through tinkering (which I would consider a form of hacking). What usually would happen is I would try to upgrade something, break my computer, and then spend the next four hours trying to fix it. The problem here is that you would be breaking the 'fixer' with no time to google how to roll back the buggy changes.

      In a research done by Liebetanz on rats, it appeared that it would take tDCS current density of 142.9A/m2 for durations greater than 10 minutes to cause lesions in rats brains. So if we take a tDCS device that has relatively small electrodes, like 3x3cm, we would need at least 128.61mA current for more than 10 minutes to cause any brain damage. Given that even 2mA (most typical) sessions can cause skin burns when the electrodes have been poorly prepared, the currents above 127.8mA would probably feel tortu
    • I read up about this a while ago and I recall that the sort of voltage and current provided by a 9V batter would be sufficient for the technique. I just searched again and found this [cuny.edu]. They're using about 14V to 18V and 1.5mA. So it looks pretty safe to me.

      I think it would be very hard to fry your brain with a 9v battery, even if you couple it to your head with saline soaked sponges. It'd sting, but it's doubtful you'd be able to endure enough to do serious damage. If you want to exercise an abundance of caution, you could put a 2ma or 5ma fast blow fuse in series with the electrode (yes, they make them that small).

      More to the point is *subtle* changes in your brain because you hooked the electrodes up wrong, or overstimulated your brain with long sessions without medical supervision. You could commit a fatal error if you are treating yourself for depression and you connect the device in a way that makes the depression worse.

      One thing that's worth noting is tha most if not all the claimed benefits of tDCS can be achieved through exercise. That's worth considering as an alternative brain hacking scheme.

        You make Niven sound like a bad writer, when he is merely mediocre. He never, for example, takes extra time to piss on your mind simply because he can. Now, Piers Anthony, he is a bad writer. Actively bad.

        And hot dogs can be good without being a delicacy. Or truly fit for human consumption.

Or decided to write the first sci-fi troll novel. I think B is infinitely more likely.

  • The kind of people who actually would have the means, motivation, and wherewithal to do this probably face at least as much risk and danger in their everyday hobbies and activities. (Serious tinkerers and the like who play with electricity, fire, chemicals, metalworking tools, lasers, plasma cutters, etc. day in and day out.)

    It's when the technology goes 'As Seen On TV' and Joe Six-Pack can buy himself an "Easy-peasy dew-it-yerself brain-zappery kit" that the question of safety truly becomes relevant.

      Some people claim to have learned to understand various sorts of mathematics rapidly through the use of LSD, why not electricity? We only have vague notions of how memory or indeed thought actually works, we can only measure which parts of the brain are working so far. Big achievement to be sure, but it's hard to say what might be effective. Which is why it's daft to make yourself a guinea pig. Who knows what you will achieve, regardless of your intent?

      • by tgv (254536)

        We might not know much about memory, we do know that language learning requires many, correlated changes in the brain. You need to learn to identify German words, their meanings, classes and features, the rules which operate on these classes and their exceptions, and the combination of meanings, plus all kinds of idiomatic, opaque expressions. You cannot expect a bit of electricity to facilitate making those changes to all these different processes and still be "compatible" with each other much faster. And
