The mind and our senses, does it make sense

Hi there,

This is an extremely interesting subject. From my brief readings, it seems like for people who are blind and not blind, it requires a combination of all senses to form images. Images, it appears are not the result of vision alone.

Also, there is some controversy concerning the forms and shapes that congenitally blind people describe.

It is a fascinating subject and I am looking forward to what others have to say on this subject.

Im pretty sure blind people from birth dont dream visually. Hence the old saying "talking colors to a blind person."

It all depends on which portion of the visual processing sectors of the brain are affected.

While it is a very interesting area of inquiry, as I, personally, find all of the area of neurological matters; it is not quite as mysterious a matter as some may feel it to be, however.




This is an important point, because there is a difference between having signal input problems to a fully operative cortical area (V1~5), and having areas of the occipital lobe being dead. Also, in that there are two primary paths, and one can project to the visual cortex without the other, there can be cases where there is no reportable vision (dorsal damaged) but some motor actions can reveal that the ventral pathway is evidently open and working. Things related to this, however, I intend to post in other places so it might be good to keep an eye open there too (Consciousness is a Biological Problem thead).

Very interesting.

I have read some articles about a phenomen called "blindsight" . A person is technically blind, they can see nothing, however in random selection tests they achieve better marks than one would achieve by guessing. They attached electrodes to see if the patients were "faking" there blindness, and the areas normally associated with vision were inactive. They suggested that some very minor nerve tissue which branches from the optic nerve which is normally associated with the body clock where being used to have some type of instinctive vision.

As for the question at hand, I have no idea, and would love to know if there are any studies which can shed more light on this. After seeing my baby twitching in his sleep from several weeks old, it made me wonder what he could possibly be dreaming of, seeing as though he only really had one concept, and that was sucking for milk.

Dear "ahmedjbh" from Neptune!
Greetings;

I'm a new comer here reading your posts.Unfortunately I'm not as wise as you to be just serious;so you may see a few humors in my posts,sensible of course!:bigsmile:

Several years living on Mars,one of my interests is looking at the "Earthly" people who are sweating in their "Cars".

You may look at the fishes in their jars ,it makes no difference!
But try to choose the philosopher fishes to be detected!!:detective:
It is a pleasure to watch the confused rigid philosophers who are radiated in the universe!!!

Well;suppose you are watching a "red" fish swimming in a "green" jar.The fish is passing through the glass to reach your beautiful retina!You may see the fish,for it is in a constant journey to your eyes , to be picked up finally by different eyes or cameras!

Suppose there isn't any eye;
well,how many bodies are there for the radiated fishes who are passing the glasses as the limpid walls!?:shocked:

Suppose the watching one is "color blind"!What will be the result?!


Hmmmmm.... let's be back to the dear filosofired's question after the break:



Suppose you're watching a "red" fish who is swimming in a "red" jar.You may not see the fish even though you're not blind.Does the fish realy pass the red glass?!Even if the watching one is a color blind!?:brickwall:

By the way if it is the fish who passes the glass to reach your eyes,or you are the one who are passing the glass to pick up the fish?!



Thanks and regards/
Yours/"Blessed Lunatic Wiseman"!

My dreams don't always involve clear visual images. In fact most of the time it's more conceptual. I dream of a white dove, but I just know it's white... I don't actually see it.

Only twice in my life have I dreamed in color. One dream was a weird art exhibit in which different artists were all presenting portraits of my cousin. The dream consisted of one portrait after the other. At first they looked like my cousin, but then changed to depicting his spirit. I saw a succession of bucking bull type images in red, black and blue.

Once I had a dream with no visual aspect. The best I could do to explain it would be to say it was like a beehive with a queen bee who was in communication with thousands of bees in the environment. The substance of the dream was a strong sense of accomplishment the bees felt. But there weren't any bees... that's just a metaphor. Am I the only person who has dreams like that?
