Brain regions do not communicate efficiently in adults with autism

A novel look at the brains of adults with autism has provided new evidence that various brain regions of people with the developmental disorder may not communicate with each other as efficiently as they do in other people.

Researchers from the University of Washington's Autism Center will report today at the annual meeting of the Society for Neuroscience on the first study that measures neural activity by using high-resolution electroencephalography (EEG) to examine connections in the cerebral cortex, the part of the brain that deals with higher cognitive processes.

Compared to normally developing individuals, the scientists found patterns of abnormal connectivity between brain regions in people with autism. These abnormalities showed both over and under connectivity between neurons in different parts of the cortex, according to Michael Murias, a postdoctoral researcher who headed the study.

"Our findings indicate adults with autism show differences in coordinated neural activity," said Murias, "which implies poor internal communication between the parts of the brain."

The UW researchers analyzed EEGs from 36 adults, ranging in age from 19 to 38. Half the adults had autism and all had IQs of at least 80. The EEGs, which measure the activity of hundreds of millions of brain cells, were collected with an array of 124 electrodes while the people were seated and relaxed with their eyes closed for two minutes.

The researchers found patterns of higher than normal neural connectivity in the left hemisphere, particularly in the temporal lobe of the persons with autism within two different frequencies of brain waves, the delta and theta bands. This part of the brain is associated with language, which is impaired in many people with autism.

A global pattern of decreased neural connectivity between the frontal lobes and the rest of autistic brain showed up on the alpha wave band. These findings support s
