Circuits underlying social function and dysfunction.
Social skills rest on different brain circuits; the review shows which circuit fits which skill so you can aim your teaching better.
01Research in Context
What this study did
Wang et al. (2023) wrote a narrative review. They mapped brain circuits that control different parts of social behavior in autism.
The authors sorted social skills into clear domains. They then named the brain networks tied to each domain.
What they found
The review shows two key ideas. Some brain circuits are shared across many social skills. Other circuits only serve one domain, like eye contact or turn-taking.
Knowing which circuit does what can guide future precision treatments.
How this fits with other research
Laties (2008) came first and blamed mirror-neuron faults for most social trouble. Ziwen et al. widen the picture by adding reward, language, and sensory circuits.
Li et al. (2025) give fresh proof. They found weak right-side social-visual connections in kids with autism. The weakness tracked with social symptom severity. This supports the domain-specific part of the new map.
McCormick et al. (2025) and Kinard et al. (2020) both show blunted brain reactions to social rewards. Their data fit the review’s call to treat reward circuits as a separate domain.
Why it matters
You can stop using one-size-fits-all social programs. Look at the learner’s weakest domain, then pick tools that match that circuit. Eye-contact issues? Target visual-attention hubs. Lack of joy in play? Build in strong nonsocial rewards first. Use the map to choose goals and to explain to parents why you are starting there.

03Original abstract
Substantial advances have been made toward understanding the genetic and environmental risk factors for autism, a neurodevelopmental disorder with social impairment as a core feature. In combination with optogenetic and chemogenetic tools to manipulate neural circuits in vivo, it is now possible to use model systems to test how specific neural circuits underlie social function and dysfunction. Here, we review the literature that has identified circuits associated with social interest (sociability), social reward, social memory, dominance, and aggression, and we outline a preliminary roadmap of the neural circuits driving these social behaviors. We highlight the neural circuitry underlying each behavioral domain, as well as develop an interactive map of how these circuits overlap across domains. We find that some of the circuits underlying social behavior are general and are involved in the control of multiple behavioral aspects, whereas other circuits appear to be specialized for specific aspects of social behavior. Our overlapping circuit map therefore helps to delineate the circuits involved in the various domains of social behavior and to identify gaps in knowledge.
