The Brain Sees What We Don't

Recommended Posts

Your brain sees and does more than you know, according to a new study that points to the mysterious workings of the unconscious mind.

 

To come to this heady conclusion, scientists had to zap the brains of healthy volunteers (and rather brave ones, we might add) and temporarily shut down the part of the brain that processes visual information. For a fraction of a second, a pulse of energy called transcranial magnetic stimulation shut down each person's visual cortex. That's the part of the brain known to process what we see.

 

The volunteers stared at a computer screen during this moment of blindness while a simple image flashed for an instant.

 

See that?

 

The scientists then asked the study subjects if they had seen a horizontal or vertical line in one test, and a red or green dot in the other. All nine of them said they'd seen nothing each time.

 

When asked to guess what they'd seen, however, they did significantly better than 50-50.

 

Those who'd been blind witness to a line guessed its orientation accurately 75 percent of the time. Those who'd been shown a dot guessed its color right in 81 percent of the cases.

it consumes 20 watts of power - enough to illuminate a light globe

well, it's cool since this thing kinda enters the category of "mind vision" or "the eye of the mind" if you think 'bout it. one of my most powerful convictions is that when we do unlock the brain's secrets we gain alot of cool new powers.
