Summary

Neuroimaging techniques have demonstrated a neuroanatomical basis for various psychiatric disorders. In particular, alterations in the structure and function of the prefrontal cortex and limbic system have been implicated in depression, anxiety, and addiction. Insights about the neural etiology of psychiatric disorders can foster the design of appropriate treatment plans targeting specific neural substrates. This section discusses specifically the anatomy and function of the basal ganglia, a group of brain structures involved in modulating motor and executive functions, including the organization of cortical connections and pathways involved in goal-directed behaviors. The following sections provide information on the anatomy of the temporal and frontal lobes, including their surfaces, gyri and white matter connections within the cerebral hemispheres. Finally, ascending neurotransmitter systems are described in detail.
