Children with autism lack a key brain activity that would normally help them understand the feelings and intentions of others, according to a groundbreaking study by UCLA researchers.
New magnetic imaging research has shown that, unlike in normal children, the mirror neuron system in autistic children fails to work while they imitate and observe emotions.

Normally, mirror neurons fire when a person takes action or observes the same action taken by others. For example, when a girl skips rope, her mirror neurons fire in the inferior frontal gyrus of the brain. When observed by a nonautistic friend, his mirror neurons become active, as well. New studies suggest such brain activity leads us to automatically understand what people intend and how they feel.
Autistic children, however, often misunderstand verbal and other cues suggesting anger, joy or other emotions in others. In short, they lack a mature sense of empathy. What UCLA researchers found was that the more autistic symptoms a high-functioning autistic child demonstrated, the less his or her mirror neuron system functioned.
