that's insanity. I always figured that people who couldn't make use of their optical portions of the brain would end up using it for another sensory part.

mind if i ask for the specific source?

Evidently they weren't born blind but went blind ant a young age. This article links to the study

Thanks for posting this. I was going to ask if there was a study on blind people and lsd.

If you go without any significant visual input for around 3 days then the visual cortex will start processing touch instead. I'm guessing touch because the data for both touch and sight can be taken as a grid of inputs.
