I (the Royal I, that is to say: my wife) have heard about this new technique wherein they are using 3D imaging of facial planes to detect and diagnose autism. am particularly interested in what features they are examining and what identifying differences they are interested in. I've been looking around, but keep finding red herrings (imaging of cortex convolutions as opposed to facial, or imaging to diagnose other diseases such as Down's). I also find articles that don't go into details. Anyone got any leads?
