This volume provides an account of the critical contribution the orbitofrontal cortex makes across the limbic, striatal, and prefrontal networks and discusses the implications of orbitofrontal dysfunction in addiction, aging, and psychiatric disorders.

The topics addressed include: The definition of orbitofrontal cortex across species; The role of orbitofrontal cortex in chemosensory function; Associative learning and response inhibition; The importance of connections to limbic, striatal, and prefrontal regions; and The role of the orbitofrontal cortex in disease.
