Neuropsychiatry links psychiatric symptoms to brain-body function as the following examples indicate:

• ·      Psychiatric Disorder—Dysfunction in brain structures & brain neurocircuits
• ·      Depressive Disorder—Limbic-cortical dysregulation
• ·      Obsessive Compulsive Disorder—Frontal-subcortical circuitry, right caudate dysfunction
• ·      Schizophrenia—NMDA receptor activation in the prefrontal cortex
• ·      Bipolar Disorder—Prefrontal cortex, hippocampus, and amygdala dysfunction

Medication, neurosurgery, brain stimulators, or structural implants are chosen based on the dysfunction in the brain structures and brain neurocircuits.
