An interesting question. It is certainly true that deaf people seem to have enhanced visual skills. I have worked with deaf pupils for many years and their use of periferal vision, for example if they are playing fotball, is great. However, whether this is through honing the visual skills through necessity or by the audio parts of the brain compensating is difficult to say. Most "deaf" people in fact do have some usable hearing - it is not that the audio parts of the brain are not needed, but that the messages are not getting there well. So they still need this part to work on hearing, albeit impaired. Having said that, someone who is completely deaf or chooses not to use hearing aids, may be able to train the audio parts to work on vision, rather like a person after a stroke retraining parts of their brain for speech or mobility.
