A study by researchers at the University of California, appearing in the latest issue of Proceedings of the National Academy of Sciences says that people with autism never "daydream" The researchers arrived at this conclusion after comparing the brain scans of people having autism and those not affected by the disease.

During the resting period of the brain, emotions and thoughts are processed. However this does not happen in autistic individuals. Scientists speculate that such patients are awkward socially since there is no daydreaming network. Regions of the brain like the "medial prefrontal cortex, the rostral anterior cingulate and the precuneus" are pretty active during this stage.

Using fMRI (functional magnetic resonance imaging) scans; the researchers monitored 15 autistic patients and compared their scans with 15 healthy individuals. They found that the rest period activity was absent in autism-affected individuals.

"We speculate that the lack of deactivation in the autism group is indicative of abnormal internally directed processes at rest, which may be an important contribution to the social and emotional deficits of autism," the researchers wrote.

Commenting on the study, Richard Mills, director of research for the National Autistic Society and Research Autism said, "This study sheds further light on the neurological factors involved in autism and some of the possible implications for differences in the cognitive profile and social behaviour."

What causes autism? How about 187 mcg of mercury via vaccines before the age of six months. Everyone should read the results of the UC Davis Study and the study conducted at Columbia University by Mady Hornig involving the infant mice. One third of the infant mice given per ratio of mercury laden vaccines, displayed behavior abnormalities. There is NOT ONE scientific study proving it safe to vaccinate infants let alone inject them with the 187 mcg of mercury that was present in the ‘90’s vaccines. Also, Dr. Wakefield’s study of measles in the stomach caused by the MMR is gaining recognition by other scientists around the world. For many children, the multitude of vaccines given before the 15 month MMR alters the immune system's ability to cope with the live virus in the MMR vaccine. Three large groups who do not vaccinate, Christian Science, Amish, and home-schoolers, do not have autism nor the mirage of other behavior disorders. This is extremely significant.
