Abstract: 

Brain imaging study reveals individuals with autism have a ticker cortex with more folds. This suggests that differences in cognitive abilities of people with autism could be due to unique brain structures.

Abstract: 

Using diffusion magnetic resonance imaging, researchers found cerebral fiber pathways formed a rectilinear three-dimensional grid and Cortico-cortical pathways formed parallel sheets of interwoven paths in four nonhuman primate species and in humans.

Abstract: 

MEG study finds diminished long-range and local functional connectivity as individuals with ASD viewed faces. The study challenges the popular assumption that only long-range connectivity is reduced in ASD.
