Autism in Fragile X Syndrome; A Functional MRI Study of Facial Emotion-Processing

Andrew G. McKechanie, Sonya Campbell, Sarah E. A. Eley, Andrew C. Stanfield
2019 Genes  
Previous functional imaging studies of fragile X syndrome have typically focused on those with fragile X syndrome compared to either neurotypical or autism spectrum disorder control groups.  ...  Individuals in the autism group had a region of significantly reduced activity centered on the left superior temporal gyrus, compared to those with FXS alone, in response to the fearful faces.  ...  One of the central features of autism is a difference in reciprocal social communication and interaction. What underlies this from a biological basis has been the basis of a number of theories.  ...
