Inferior Parietal Area
Autism spectrum disorder (ASD) is characterized by altered connectivity in cortical regions, such as the inferior parietal lobe, involved with communication and emotion regulation (Hanaie et al. 2016). The inferior parietal lobe integrates sensory and motor information to generate spatiotemporal representations (Hanaie et al. 2016). Among ASD patients, several studies have shown reduced gray matter and cortex in the inferior parietal lobe (Brieber et al. 2007; Wallace et al. 2010). Furthermore, these studies suggest that cortical thinning of the parietal and temporal cortices results from abnormal cortical growth in ASD patients (Wallace et al. 2010). Further research is required to elucidate the atypical neural growth and developmental mechanisms observed in ASD patients.
