why should you be afraid of Knowledge?

come, have a bite.

The accurate identification of obscured and concealed objects in complex environments was an important skill required for survival during human evolution, and is required today for many forms of expertise. Here we used transcranial direct current stimulation (tDCS) guided using neuroimaging to increase learning rate in a novel, minimally guided discovery-learning paradigm. Ninety-six subjects identified threat-related objects concealed in naturalistic virtual surroundings used in real-world training. A variety of brain networks were found using fMRI data collected at different stages of learning, with two of these networks focused in right inferior frontal and right parietal cortex. Anodal 2.0 mA tDCS performed for 30 min over these regions in a series of single-blind, randomized studies resulted in significant improvements in learning and performance compared with 0.1 mA tDCS. This difference in performance increased to a factor of two after a one-hour delay. A doseâ€“response effect of current strength on learning was also found. Taken together, these brain imaging and stimulation studies suggest that right frontal and parietal cortex are involved in learning to identify concealed objects in naturalistic surroundings. Furthermore, they suggest that the application of anodal tDCS over these regions can greatly increase learning, resulting in one of the largest effects on learning yet reported. The methods developed here may be useful to decrease the time required to attain expertise in a variety of settings.
Research Highlights

â–º We developed a task in which subjects learned to identify threat-related objects hidden in naturalistic surroundings. â–º We used this task in a combined brain imaging and stimulation study in a total of 96 subjects. â–º Brain networks found to be more active after training included right inferior frontal and right parietal cortex. â–º A doseâ€“response effect of current strength on learning was found. â–º 2.0 mA TDCS over frontal and parietal brain regions resulted in a two-fold improvement in learning and performance. â–º TDCS may be useful to reduce training time to achieve expertise.

Yeah,,,, but do they know how to start a fire in the woods, change a tire on a motor vehicle or think about the consequences of their actions in pursuit of immediate gratification?

Knowledge is one thing and wisdom is another. Until appropriately applied to real-world scenario, knowledge has no meaning. Learning to do something without discovering why, or how it functions and the basic understanding of cause and affect is nothing more than mechanization of humanity.

My point is,,,, are we really any smarter today with all this information at our fingertips than we were centuries ago? Sure major construction projects took generations to complete. But many still stand today. We have a hard time getting thirty years out of a modern bridge without major overhauls.

When those electric gadgets have no juice and the batteries go dead,,,, does anyone honestly think our generation would survive better than our ancestors?

I guess that's even worse than being Werner von Braun.

Has anyone ever considered the idea that since we started bottling so much water, there is less water actually cycling around the earth and more water being aged in plastic containers? Is it enough to affect the climate?

How come CO2 is now considered a pollutant yet we pump it into soft drinks ad infinitum?

If the polar bears are running out of decent living conditions, why are there FIVE TIMES their population today than 40 years ago?

If a battery dies, why do we not call them alive instead of charged?

When Santa makes his list of who's been good and who's been bad, is that according to the culture of the subjects upbringing? Is the bomb maker in Pakistan good or bad in their culture? Does the pornstar who brings so many smiles to millions get on Santa's good list? or bad?

A big part of that is due to the fact that people are no longer allowed to just go out & shoot them like they were up until the '50's & '60's.

Also "running out of decent living conditions" is a misnomer- not all polar bears rely on sea ice, and some sub-populations are increasing because they're able to take advantage of the change in climate.

Same reason there are more American bison than there used to be.

It's amazing how populations grow when you stop killing them indiscriminately.

yes, i know.

now would somebody please turn off the terrible country music that i'm currently picking up by mistake.

i hate that song about beer, and women and god being crazy...

Sorry, Simon, that's pretty much the only song there is.

God may not be crazy but he could use a little help with his Manic Depression Type II (once now as Bi-polar).

Rapid cycling?

Tell god to try abilify.

Abilify...jesus....how about possibleserioussiseeffectsanol
Or maybe gollytrythisahine?

And when youre there FT, ask God who the fuck came up with THAT name...

Nice try, but i know my DSM IV better than you do, toots.

FaeTora · Post by **FaeTora** » Thu Dec 23, 2010 7:54 pm

If you call me toots one more time, I will hang you from my wall.

Simon of the Playa · Post by **Simon of the Playa** » Thu Dec 23, 2010 9:12 pm

Will i be well hung?

Trishntek · Post by **Trishntek** » Thu Dec 23, 2010 11:11 pm

So would the proper term be hung "by the balls?" or "from the balls?"

edit: it's a prepositional conundrum I tell ya,,,,,,

If you call me toots. I will feed you your own set and hang you by anything that hurts.

I HATE HATE HATE that FUCKING term.

I am not anyone's god damn fucking TOOTS!

Sorry. Its just my thing. It doesn't dangle but its there.
