Brodmann Area 9, Superior View

Description

Brodmann area 9 occupies the dorsal prefrontal cortex on the superior and middle frontal gyri, seen here from a superior (dorsal) viewpoint across the anterior frontal lobe. Along the midline, the interhemispheric fissure separates the right and left hemispheres, placing BA9 lateral to the fissure and superior to the superior frontal sulcus where that landmark is visible. Posteriorly, the region approaches the premotor cortex (Brodmann area 6) near the precentral sulcus, while anteriorly it extends toward the frontal pole. Sulcal anatomy sets the boundaries. Brodmann area 9 is routinely discussed in relation to executive control and working memory networks, and focal injury here can present as a dysexecutive syndrome with impaired planning, set shifting, and behavioral regulation despite preserved primary motor and sensory function. Psychiatric literature often links dorsolateral prefrontal cortex (classically BA9/46) to schizophrenia and major depressive disorder, and neuromodulation protocols for depression frequently target this cortical territory. Spatial context helps. The superior perspective supports teaching and figure preparation because it orients BA9 relative to midline landmarks and the perirolandic region without distraction from ventral orbital anatomy. Neuroanatomy and neuropsychology courses can pair this illustration with case discussions on frontal lobe lesions, frontal stroke syndromes, and neurodegenerative disorders with frontal involvement, including frontotemporal dementia. Cognitive neuroscience and psychiatry publications will also find it well suited for figures on prefrontal circuitry, fMRI task activation maps, and transcranial magnetic stimulation targeting rationales when a dorsal prefrontal label is needed.
