Well, deaf people might argue that [...]
That's an interesting question.
Of course, nerves don't transport the QUALITY of a sensation.
(Like: This is what you SEE, this is what you HEAR)
Once the signal has passed your senses there's no way to differ between the original sources
(that's why induced signals could seem real, like in 'Matrix' or - more scientific - the 'Brain in the Vat'). It is only the AREA in ones brain, that tells him: this was seen, this was heared, that was smelled, etc.
So it should be possible to induce the illusion of 'sound' even in the brain of a deaf person, by stimulating the corresponding brain-area.
But then -
If one is BORN deaf, the surrounding areas would already have been taken over the 'un-used' parts of the brain, which would otherwise be there for proceeding information from 'hearing'. These areas don't just remain plain 'empty' or 'unused'. So it COULD be, that there is no way to stimulate the specific brain-area of a deaf-born person, simply because there is no such area.
As I said: Interesting question.
I don't own the solution. But maybe I'll look it up one day.
