ventrolateral prefrontal cortex

ventrolateral prefrontal cortex (VLPFC)

The term ventrolateral prefrontal cortex refers to the more ventral 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 inferior frontal gyrus. It is found in both the human and the macaque. It is composed of area 44 and area 45. Some authors include the lateral part of area 47, area 47l, which is located at the ventrolateral margin of the frontal lobe ( Petrides-2012 ). That, as one of four components of area 47, is more parsimoniously considered part of orbitomedial prefrontal cortex. The other component of lateral prefrontal cortex is the dorsolateral prefrontal cortex ( Petrides-2012 ). The lateral prefrontal cortex has no equivalent in the rat ( Preuss-1995 ).

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'.
