Autism warning: One ‘well-known symptom’ of the condition that you can see

When constrained to focus on the eye region of someone’s face, the autism group experienced an “over-activation” of the brain’s subcortical system.

“The findings of the study support the hypothesis of an imbalance between the brain’s excitatory and inhibitory signalling networks in autism,” the authors stated.

“Excitatory refers to neurotransmitters that stimulate the brain, while inhibitory refers to those that calm it and provides equilibrium,” the researchers elaborated.

The root of such an imbalance has been said to be the result of diverse genetic and environmental causes.
