Posted on 11/03/2005 9:59:54 PM PST by JRios1968
THE uncanny ability of blind people to "sense" unseen objects has been demonstrated for the first time in sighted volunteers whose vision was blanked out by scientists.
The findings suggest "blindsight", which has been observed in blind people whose eyes function normally but who have suffered damage to the brain's visual centre, is a real and not imagined phenomenon.
In tests, the blind have been able to distinguish basic shapes of objects they cannot see, as well as their orientation and direction of motion. On other occasions a blind person has reported experiencing a "feeling" that an object is present, while not being able to see it.

I always thought it was lame that they come up with the "5 senses" bs.
There's gotta be alot more than just 5. Sense of temperature, sense of balance, sense of time, sense of motion.
"Scientists from the University of Houston in Texas, temporarily blinded a group of 12 volunteers by using an
electromagnetic field to shut down the primary visual cortex. "
Were these people nuts? do not try this at home!
"And sense of style!!!!"
I hope they paid them well...
I wouldn't take the chance that it was temporary. How'd they know it wouldn't be permanent? A blindfold could've done the job.
It said they were volunteers! You couldn't pay me enough to do it that way.
Third Eye Chakra Bump
I saw on tv awhile back a blind guy that does "echolocation" or whatever its called. He makes various cliking noises and hears the echoes. It was pretty amazing. Pointed to a tree 20' away, the camera's light reflector sheet ("broad thin material") and "a pole of some sort a few feet away" (light boom - 1 to 2" in dia). He teaches other deaf people how to do it (and they had them on the show too).
Sense of Fagdom? Hey, new word!
There is so much we do not know.
Wow! Real life bat Man.
I guess you can't really lump that in with hearing.
I mentioned time because it's really amazing, I don't have a fixed schedule.
But nine times out of ten, when I wake up, I know what time it is within about ten minutes.
The way I know if I really got a good sleep is if I wake up and don't have not the smallest clue what time it is.
I can "see" (no pun intended) some logic in this..if the eyes still process and can feed the info to brain but the brain's visual centre can't process it to normal sight you still might perceive some kind of non visual impression
Phantom feeling in an amputee is some time just a mirror echo of the remaining limb to the amputated side, kind of a brain crosstalk
There's something like nine human senses. Touch, smell, sight, hearing, taste, nociception (pain), equilibrium, kinesthesia (location of your body parts), and temperature, IIRC.
It's probably echo location going on. For instance, hi end headphone amplifiers have circuitry built in to produce the sound delay that comes from different location of speakers - i.e the time it takes for sound to get from one side of your head to the other. This allows more "head space" - the ability to note the location of instrument on the sound stage. I'm sure this same thing is going on when people have their eyes closed and ears open.
I'd trust the blindfold results better, too.

whatever happened to a blindfold?
Yo man, can you lend the $25 it takes to see this? ;-)
Sleeping pills are cheaper...
I just wanted to put the reference info here.
I don't think that this is new. There was a series on television where a famous British-Indian brain specialist (based at a uni in California somewhere) analysed the brain by showing the results of various forms of brain damage.
There was one person whose sight was disabled in a car accident. It wasn't his eyes that were damaged, but the part of his brain that dealt with vision. Even though he couldn't see any objects, he *could* detect motion, and could say, with 100% accuracy, in which direction an object in front of him was moving. They showed that there was a secondary part of the visual components of the brain, which processes these things subconsciously, and it was undamaged in this particular man.
It is this part of the brain which deals with reactions and what have you (the guy would blink if something were flicked near his eye). Really cool series: it was shown on Channel 4 in the UK about 5 years ago.
Thanks. Any good links - save me the trouble of poking around the web?
...we're gonna need a new scam!
This is amazing (brain-machine interface) stuff.

Sure. Most of the neuroscience and brain mapping withing universities are partly funded by DARPA. This is for the brain-machine interface program.

MUSC To Develop Brain Stimulation Device For Military
CHARLESTON, SC -- The Defense Advanced Research Projects Agency (DARPA) announced today that it has awarded the Medical University of South Carolina (MUSC) a Phase I/II contract to develop a portable brain stimulation device for use by the military to alleviate the effects of sleep deprivation on soldiers' performance. The contract, entitled Creating a Man-portable Transcranial Magnetic Stimulation System (TMS) to Improve War-fighter Performance
See: Miguel Nicolelis from Duke University, North Carolina implanted about one hundred electrodes into brains of an owl monkey and used the recorded signals to muscles to control a robot arm.
I'd heard of blind people who could accurately detect flashes of light, too. The conclusion was much the same, that the visual part of seeing isn't all there is to what we call sight. Fascinating stuff.
