It has been suggested that deficits in higher-order cognitive functions serve as intermediate phenotypic indicators of genetic vulnerability to schizophrenia. The dopamine hypothesis of schizophrenia postulates that insufficiency of dopamine transmission in the prefrontal cortex contributes to the cognitive deficits observed in patients with the disease, and there is robust empirical evidence for a central role of prefrontal cortex dopamine D(1) receptors in working memory functions.
