The mirror neuron system (MNS) theory of autism hypothesizes that disrupted development of the MNS impairs autistic people's ability to imitate others, leading to core autistic features of social impairment and communication difficulties. In animals, the MNS activates when an animal performs an action or observes another animal perform the same ...

Identical twin studies put autism's heritability in a range between 36% and 95.7%, with concordance for a broader phenotype usually found at the higher end of the range. [28] Autism concordance in siblings and fraternal twins is anywhere between 0 and 23.5%. This is more likely 2–4% for classic autism and 10–20% for a broader spectrum.
One of the leading theories of a potential pathogenic process in ASD is cortical hyperexcitability. Maintaining proper levels of cortical excitability is essential for many important cognitive functions, such as processing sensory information, [18] communication between different regions of the brain, and neural plasticity.
