not so.... my grandson does not find humor or interest in many things I or the typical person would. Yet can find extreme humor in things we don't even notice. So the idea that his brain doesn't fire off to facial gesturing the same as mine would is really interesting. We have always known that autistic people can't relate to emotional cues. Depending on the level of severity there are more noticeable differences. Someone on the low will react completely different than someone with Aspergers. No one suggests they are brain dead.... but they definitely relate differently. So when my grandson intently looks into my eyes....I feel a sense of connection that fires off synopsis in my brain...this small study is just suggesting those same firing are not happening with him ....hence the possibility of finding some answers to this very complex this called Autism.
