Document Summary
Reduced activity between areas during language processing. Amygdala fewer cells fewer dendritic connections. No influence on pfc during face perception cerebellum: fewer cells fewer dendritic connections. Many of the studies were done as autopsies, bias sample. Prefrontal cortex: fewer cells fewer dendritic connections: newer research shows to many connections in prefrontal cortex lower blood flow and task-related activity temporal lobe & ffa: fewer cells. Abnormal ffa activity in face perception, object processing occurs instead. Only fire for own activity, not for others. But recent (2010) studies find normal mirror neuron activity in autism. We don"t think there is any significant difference, maybe a subset of individuals with autism who display these abnormalities reduced corpus callosum size. Neuron transport is different in these individuals. Excessive connections in frontal cortex; too few with rest of brain. Reduced long range connectivity between prefrontal cortex and the rest of the brain intense world theory. Elevated blood levels in 33% of autism patients.
