The autism group saw an over-activation of brain’s subcortical systems when they were forced to concentrate on their eyes.
The study supports the idea that autism is caused by an imbalance in the brain’s excitatory signalling network and the inhibitory signalling network, the authors said.
Researchers explained that neurotransmitters which stimulate the brain are called excitatory, and inhibitory those that maintain equilibrium.
It has been suggested that the root cause of this imbalance is due to a variety of genetic and environmental factors.
