The dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the primate brain. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts into adulthood. [1] The DLPFC is not an anatomical structure, but rather a functional one.
Brodmann area 46 roughly corresponds with the dorsolateral prefrontal cortex (DLPFC), although the borders of area 46 are based on cytoarchitecture rather than function. The DLPFC also encompasses part of granular frontal area 9 , directly adjacent on the dorsal surface of the cortex.
The ventral prefrontal cortex is composed of areas BA11, BA13, and BA14. [1] (Also see the definition of the orbitofrontal cortex.) The dorsolateral prefrontal cortex contains BA8, including the frontal eye fields. [1] The ventrolateral prefrontal cortex contains BA45 which is part of Broca's area. [20]
Brodmann area 9, or BA9, refers to a cytoarchitecturally defined portion of the frontal cortex in the brain of humans and other primates. Its cytoarchitecture is referred to as granular due to the concentration of granule cells in layer IV. [1] It contributes to the dorsolateral and medial prefrontal cortex.
The frontoparietal network (FPN), generally also known as the central executive network (CEN) or, more specifically, the lateral frontoparietal network (L-FPN) (see Nomenclature), is a large-scale brain network primarily composed of the dorsolateral prefrontal cortex and posterior parietal cortex, [4] around the intraparietal sulcus. [5]
Area 46 – Dorsolateral prefrontal cortex; Area 47 – Orbital part of inferior frontal gyrus; Area 48 – Retrosubicular area (a small part of the medial surface of the temporal lobe) Area 49 – Parasubicular area in a rodent; Area 52 – Parainsular area (at the junction of the temporal lobe and the insula) (*) Area only found in non-human ...
In human brain anatomy, the lateral prefrontal cortex (LPFC) is part of the prefrontal cortex (PFC). According to Striedter [1] the PFC of humans can be delineated into two functionally, morphologically, and evolutionarily different regions: the ventromedial PFC (vmPFC) present in all mammals and the LPFC present only in primates.
The mesocortical pathway is a dopaminergic pathway that connects the ventral tegmentum to the prefrontal cortex. It is one of the four major dopamine pathways in the brain . It is essential to the normal cognitive function of the dorsolateral prefrontal cortex (part of the frontal lobe), and is thought to be involved in cognitive control ...
