the man who mistook his wife for a hat

In the story "The Man who Mistook His Wife for a Hat" Dr. P's eyes were not messed up but the visual parts of his brain or the occipital lobes, were malfunctioning. however the temporal lobes seemed to be taking place of the occipital lobes in converting the sounds he was hearing into pictures or otherwise causing him to see. I think that the axon fibers were connected wrong and somehow substituted his occipital lobes for his temporal lobes. In "the lost mariner" he lost all of his memory after he got out the marines in 1945. I think that some damage was caused to his Hippocampus during the war causing his memory to be affected. severe damage must have been caused because his memory is so short term.
