The clip shows that the senses enter the tongue and, eventually, make their way to the visual cortex. So, the blind person's brain is actually making the stimulation of the image and, therefore, the blind person is actually SEEING? Or is it more like braille, where it's a different pattern, but it can be read via touch? Is this a matter of the same or different 'brain language'?
"We see with our brains not our eyes." "When a blind man uses a cane, he sweeps it back and forth, and has only one point, the tip, feeding him information through the skin receptors in the hand. Yet this sweeping allows him to sort out where the door jam is, or the chair, or distinguish a foot if it hits it, because it will give a little. Then he uses this information to guide himself to the chair to sit down. Though his hand sensors are where he gets the information and where the cane interfaces with him, what he subjectively perceives is not the cane's pressure on his hand but the layout of the room: chairs, walls, feet, the 3-d space. The actual receptor surface in the hand becomes merely a relay for information, a data port. The receptor surface loses its identity in the process." Doidge, 2007, p. 15-16
Wow. I really do not understand how this works and I suppose I wouldn't be able to unless I tried it myself, which I really, really want to do. It is amazing how much remains untapped inside our minds and bodies. I think if we are able to reconsider everything we have been taught about limits we would discover some pretty wild stuff about our abilities as humans.

ReplyDeleteYes Chelsey! In many ways we have to unlearn what we think we know and open to possibility!
ReplyDeleteso i see how its like a pattern on tongue and the brain has to figure it out, but i didnt get if he touched the object or it could just pick it up?
ReplyDeleteThe camera sends him the shapes, that he then decodes, through his highly plastic visual cortex. He sees/feels them simaltaneously
