The document discusses atypical development and common symptoms seen in both autism and dyslexia spectra. It notes atypical information processing, poor motor skills, and sensitivity to stimuli changes as shared symptoms. All the specialties are thought to be in the neurological system responsible for methodical, regulated information processing. Two main brain types are discussed - the hunter-gatherer brain and the rancher-farmer brain. The farmer brain is a newer development in humans and any effects on brain development would impact this neurological system. Atypical individuals may show extremes of either the hunter or farmer systems.
