    What neurochemical imbalance is suggested in some models of autism?

    Answers

    An imbalance between glutamatergic excitation and GABAergic inhibitionCorrect
    Complete absence of serotonin throughout the brain
    Excess dopamine in the spinal cord
    Acetylcholine overload in the visual cortex

    Recent models propose that the relationship between excitatory and inhibitory neurotransmitters is altered, generating cortical hyperexcitability that can contribute to sensory sensitivities and processing difficulties.
