  • Note: ⇑ indicates regions where autistic participants exhibited increased cortical thickness, whereas ⇓ indicates regions where autistic participants exhibited decreased cortical thickness relative to non-autistic participants.

  • aIt is unclear from Table 5 in Ecker et al. (2010b) whether increased cortical thickness was present in the left or right anterior cingulate.
