From the Baron-Cohen lab, a pilot study finds that brain activation patterns in the parents of children diagnosed with Asperger Syndrome were different for both the embedded figure and eye empathy or emotional recognition task.
On the eye empathy test, women on average show higher levels of activation then men. This gender difference was not see among parents of AS children. In fact, both mother and father groups were lower than male controls.
It's important to remember that this is just a small pilot study. A finding such as this could also mean scientists are seeing trait variations within the population like introversion.
