I was wondering a lot about generalized pain after we learned about the eye.If nausea is the brain's response to a nonlocalized interruption of patterns, why am I not dizzy and nauseous whenever I don't wear my glasses? Would someone whose vision suddenly changed feel pain due to the new patterns of light being picked up by the eye, or does this have nothing to do with pain? Maybe I am accustomed to the changes in focus from my natural-horrible-eyesight to my glasses to my contacts, but does this change have the potential to cause the generalized interruptions that lead to pain? If people born without limbs can still experience phantom limb symptoms, could people who have severely damaged eyes or who were born blind experience pain becasue of expected pathways that are never completed? Or, if someone was born blind and missing a limb, would they experience phantom limb pain? They could not see the missing limb, but they could still feel its absence when compared to the other limb. What exactly constitutes "experiencing" these pathways in a way that their interruption causes pain?
