Research Summary
Dr. Hammer's research examines the cellular and molecular basis of schizophrenia symptoms. For example, we showed that repeated treatment with dopamine agonist drugs may provide a putative treatment for long-lasting control of schizophrenia symptoms selectively in neurons that co-express dopamine D1 and D3 receptors. Other studies reveal that posterior striatal dopamine infusion activates the auditory cortex, as occurs during auditory hallucinations.
