Probably that your brain image would look the same as majority of the brains. Would mean that most of your neurons connections are a like other peoples connections. The only problem is that all people probably have slightly different heads and brains. In some cases people have atypical brain connections, but are not attributed to autism, but they do have genetic origines. These could also fall in to synesthesia cathegory, but even synesthetics can be autistic ( I think).
