Sex hormones and neurotransmitters as mediators for sexual differentiation of the brain.
Sexual differentiation of the brain is regarded as a model for environment-dependent brain development mediated by systemic hormones and neurotransmitters. Abnormal concentrations of systemic hormones and/or neurotransmitters, if occurring during a critical period of brain development, can lead to permanent developmental disabilities of fundamental processes of life. Such developmental disabilities appear to be avoidable, at least in part, by improving the external, i.e. psychosocial and natural environment, or by correcting abnormalities in the internal, i.e. metabolic and hormonal environment and, particularly, by correcting abnormal neurotransmitter concentrations (and/or turnover rates) during brain development.
