The Plasticity of Social Brain Network in Adults With Autism Spectrum Disorder

"Social brain" refers to brain regions dedicated to processing social information and enabling us to recognize and evaluate others' mental states. The social brain hypothesis suggests that our brains evolve to navigate complex social systems. The social brain is hypothesized to consist of a distributed network including the posterior superior temporal sulcus (pSTS), the dorsal and ventral medial prefrontal cortices (dmPFC and vmPFC), ACC and posterior cingulate cortex (PCC), the amygdala, the orbital frontal cortex (OFC), and the fusiform gyrus (FG), TPJ, inferior occipital gyrus (IOG), and the insula. Each region serves distinct role while works together to support social processing, including perceiving, interpreting, and generating responses to the intentions, dispositions, and behaviors of others.
