Discussion- Can Blind People Dream?

<< < (2/3) > >>

tylerhan2000:
They can dream, but not see their dreams.
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.

:S WTF so many long words O_O too much confusion

chenna:
we (humans) know that blind people dream and we do know that they actully see things we just do not know what they see as they can not describe it as they have nothing to compair it to

Daveydude:
I believe they can not comprehend vision. What they consider visual is near impossible to comprehend without a basis.

They may claim to see visuals, but what they are is more than likely something else.

raul7legend:
Can't we just ask blind people if they dream? Cut the writing bullshit, lets just ask them XD
