It explained this with the example of the blindfolded braille readers. Over 5 days their sense of touch was enhanced, presumably at the expense of their visual senses. Over time, the visual cortex would be completely taken over if the brain was not receiving signal from the eyes.

- subaquamille 6y agoAnd that's exactly what's described at the end of the article: > If dreams are visual hallucinations triggered by a lack of visual input, we might expect to find similar visual hallucinations in people who are slowly deprived of visual input while awake. In fact, this is precisely what happens in people with eye degeneration, patients confined to a tank-respirator, and prisoners in solitary confinement. In all of these cases, people see things that are not there.
- baxtr 6y agoAnd that's exactly my point :) Shouldn't this have happened to those blind people, too?
- goodthenandnow 6y agoGood point. Also: is the visual information transmitted by the optical nerves when you don't have eyes equal as when the eyes "see" darkness?
