dorsolateral prefrontal cortex

dorsolateral prefrontal cortex (DLPFC)

The term dorsolateral prefrontal cortex refers to the more dorsal of two components of Lateral prefrontal cortex in primates. Defined on the basis of multiple criteria, it is located predominantly in the rostral parts of the superior frontal gyrus and the middle frontal gyrus. It includes area 8, area 9, area 9/46, and area 46 of both the human and the macaque ( Petrides-2012 ). The other component of Lateral prefrontal cortex is the ventrolateral prefrontal cortex. Early authors used the term "dorsolateral prefrontal cortex" to refer the entire Lateral prefrontal cortex as distinct from the orbitomedial prefrontal cortex, and some have used it in reference to other combinations of areas in the Lateral prefrontal cortex and orbitomedial prefrontal cortex ( Preuss-1995 ). Lateral prefrontal cortex is granular cortex rostral to the motor cortex and thus has no equivalent in the rat ( Preuss-1995; Wallis-2012 ).

Models Where It Appears

Topographic Model of Human Cerebral Cortex

The topographic model of human cerebral cortex is a closed partitive hierarchical model of cerebral cortical structure in the human. The cerebral cortex is segmented on the basis of internal structure, connectivity, and/or functions of cortical areas. It is designed to update the comprehensive early twentieth century parcellations of Brodmann and of von Economo and Koskinas and their successors. A work in progress, it integrates the most authoritative, comprehensive, and recent parcellations and nomenclatures from peer-reviewed publications and neuroanatomical texts. For an equivalent model in the rodent, Search BrainInfo for ' Functional CNS Model - Rat '. This segmentation of the human cerebral cortex, based on a combination of internal structure, connectivity, and function, complements the classical segmentation of the cerebral cortex into lobes, lobules, and gyri based on sulcal patterns: For the classical segmentation, see ' cerebral cortex ' and click 'Locus in Brain Hierarchy'.
