Schematic representations of the anatomy of the nasal and cerebral structures.
(A) Anatomy of the nasal cavity, lateral nasal blood supply, cribriform plate, frontal and sphenoid sinuses, prefrontal cortex structures, and subgenual cingulate gyrus. (B) Anatomy of nasal septal blood supply and some limbic system structures. ACC, Anterior cingulate cortex; ant., anterior; a., artery; dmOFC, dorsomedial orbitofrontal cortex; dmPFC, dorsomedial prefrontal cortex; lat., lateral; post., posterior; sup., superior; vmOFC, ventromedial orbitofrontal cortex; vmPFC, ventromedial prefrontal cortex.
