Just a thought I had. Schizophrenia has a physical effect on the brain. Therefore, can other aniamls, especially animals genetically close to humans, suffer from it? If so, what would the implications be for the 'consciousness' debate with the 'voices-in-the-head' effects of Schizophrenia? (I know this is not the only symptom and doesnt HAVE to be a symptom) For example, how would voices-in-the-head manifest themselves in say, a chimp? Would they be 'chimp voices'?
