    Do People Born Blind Dream?

    Do they?

    Some might say yes. But i don't think so. I think it's better for me to interview a blind. I'm not quite sure they dream because since they are born blind they don't differentiate colours. They might be able to differentiate shapes but without differentiating the colours it will going to be hard for them to dream. They were only told that the colour is either brown, red or yellow, but do they know how does the colour look like? I think they don't even know. They were taught to feel with their hands. The senses are very important to them. Let's say they touch their own mother face, they can imagine how their mother looks like but is it 100% exactly the same like what they imagine? They only know that there are nose, eyes and mouth and ears. But still, they will find it hard to imagine a person's look.

    They see the environment but hardly 'feel' the environment. They can't even interpret the happenings around them. They can only listen but difficult to interpret every little things happened around them. A successful blind person is the greatest human being in the world as the use completely their brain to think, feel and interpret everything around him. They are lawyers, Professors or whatever great positions in the community who are born blind. They listen, understand and can feel extraordinarily better than a normal human being.


    But, do they dream?

    I got this answer to this question from Yahoo. Check it out.

    No, they wouldn't. Visual stimulus is necessary for the wiring of the brain centers that process and interpret vision. The way the brain works is to develop, early in life, a huge number of neural synapses (connection points between neurons that are used in cell-to-cell signalling).

    As you grow and learn, these synapses are pared away to make the brain function efficiently, and that's the central basis of long-term learning. However, if the brain or any part of it fails to get infromation from hard-wired inputs, then that part of the brain will atrophy (at best, fringe areas of a cortical region might be adopted by adjacent cortical regions for different processes). But the take-away message here is that the brain needs visual stimulus in order to devolp the cortical regions that process vision.

    In the use-it-or-lose-it sense, the brain will not waste energy building and maintaining processes that aren't used. The optical cortex would never know how to function as an optical cortex in a person born blind.

    Or maybe they only dream what they can imagine...
