Scientists Overclock People's Brains
arshadk writes with this excerpt from the BBC about researchers at Oxford University who found that inducing a small current in a subject's parietal lobe boosted their capacity for numerical learning:
"The current could not be felt, and had no measurable effect on other brain functions. As it was turned on, the volunteers tried to learn a puzzle which involved substituting numbers for symbols. Those given the current from right to left across the parietal lobe did significantly better when given, compared to those who were given no electrical stimulation. The direction of the current was important — those given stimulation running in the opposite direction, left to right, did markedly worse at these puzzles than those given no current, with their ability matching that of an average six-year-old. The effects were not short-lived, either. When the volunteers whose performance improved was re-tested six months later, the benefits appear to have persisted. There was no wider effect on general maths ability in either group, just on the ability to complete the puzzles learned as the current was applied."
K... I just cut the cord off a lamp... somerone talk me through this O.O

What about the other sides, were the negative effects persistant? Did you just create a group of idiots? Is this legal?
Back when I worked as a mechanic, the guy that owned the place and a buddy of his used to bring cars into the shop after hours, snort up a line of blow, and go to town. I once watched them pull a motor out of a Honda Civic in 15 minutes, surgeon style (one guy giving and taking tools/nuts/bolts, one guy using the tools to remove said nuts/bolts).
No exaggeration. 15 minutes. It transcended bitchin'.

you can't improve upon the performance of your brain and your body without longterm tradeoffs
i hate that kind of defeatist, "nature/god knows best" attitude. everything you have right now is thanks to people who believed they could do better than nature, and they did. yes, you shouldn't do lines of coke to be better at your job, because that is a hack. it doesn't mean we can't make ourselves truly better, without "overclocking" and burning out. a candle that burns twice as bright could burn out twice as fast, or it could simply be a fucking light bulb that lasts 5 years.

This phenomena is quite well studied, and seems to be producing relatively linear effects. It was discovered in the 70's or so. It's refered to as transcranial direct current stimulation and just a few months ago there was a study on visual memory about the same.
It's not really new and revolutionary, it's just that the previous studies haven't been able to be worded as "OMG BRAINOVERKLOCKING!" and thus haven't generated the same interest.

Crud, then, because I and a LOT of my friends have had LASIK surgery to correct my vision. It turns out god gave me bum eyes that focused everything slightly in front of my retina, and that fixed it pretty well with minimal, if any, long-term trade-off.
My dad had high blood pressure. In spite of efforts to control it through diet and exercise, he foolishly took drugs to control it, thinking that he could improve upon his natural system to regulate it. He died a few years ago of bladder cancer. I'm not sure how exactly that was a long-term tradeoff since the doctors told us they were completely unrelated, but he seemed not to mind the short-term benefit of living a reasonably long time.
Also, where exactly do we draw the line? I mean, some people run 10 miles or more a day; surely that can't be normal and can be considered a measure to "improve on what you have," and statistically, those people tend to live longer. Do we consider eating certain foods that contain substances shown medically to lead to longer and more healthy lives, or for that matter, avoiding natural foods that contain substances shown medically to be harmful (fat, cholesterol, etc.) to be trying to improve on what we have? Before long, we'll be living in a world where technologies such as gene therapy could prevent or significantly reduce conditions like Down's Syndrome, diabetes, Alzheimer's, etc. Should we avoid those as well?
I suspect that this study is the first in a long line of research that may lead to exciting new therapies for people who might not be able to learn normally. And yes, if it's shown effective without significant side effects, it might be used much as LASIK is today, a method of improve on what we were given with little to no risk. Personally, I don't see much wrong with that. If you disagree, that's certainly your right, but I would ask that you not judge others, try to impinge on the freedom of others to make informed decisions regarding their own body, or worst of all, try to keep the research from happening that could potentially improve the lives of many people who are not able to function normally in society due to preventable or even curable disabilities.
Just some food for thought.
