What is DLPFC?
Traditionally, the dorsolateral prefrontal cortex (DLPFC) is considered as a brain area associated with domain general executive control functions such as task switching and task-set reconfiguration, prevention of interference, inhibition, planning, and working memory (e.g., Badre and Wagner, 2004; Hart et al., 2013; …
What is VMPFc?
4 Ventromedial prefrontal cortex (VMPFc) The VMPFc is located in the prefrontal cortex, and is a brain region involved in value computation that has been researched extensively in decision-making studies, due to its role in influencing the value one attaches to choices (Chib et al., 2009; Glimcher and Fehr, 2014).
Is the DLPFC in the frontal lobe?
The dorsolateral prefrontal cortex is a region of the frontal lobes that is most typically associated with executive functions including working memory and selective attention (Curtis & D’Esposito, 2003).
What is the orbitofrontal cortex responsible for?
The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making. In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area 10, 11 and 47.
Is the DLPFC part of the limbic system?
All complex mental activity requires the additional cortical and subcortical circuits with which the DLPFC is connected. The DLPFC is also the highest cortical area that is involved in motor planning, organization and regulation….

Where is the DLPFC located?
the frontal lobe
The DLPFC is located on the lateral and dorsal part of the medial convexity of the frontal lobe and comprises Brodmann’s areas 9 and 46 and a few transitional areas: 9-8, 9-45, 46-10, and 46-45 (Rajkowska and Goldman-Rakic, 1995a).
Is Ofc the same as vmPFC?
Neuronal activity in both OFC and VMPFC is closely related to the perceived value of task events. OFC neurons emphasize value information arising from visual stimuli, whereas VMPFC neurons emphasize value information arising from intrinsic knowledge or satiety levels.
What is the insula?
The insula (or insular cortex) is a thin ribbon of gray matter tissue that lies just deep to the lateral brain surface, separating the temporal lobe from the inferior parietal cortex.
What is orbitofrontal damage?
Damage to the orbitofrontal cortex can impair the learning and reversal of stimulus-reinforcement associations, and thus the correction of behavioural responses when there are no longer appropriate because previous reinforcement contingencies change.
How can the orbitofrontal cortex be damaged?
Humans suffering damage to the orbitofrontal cortex (OFC) are often described as impulsive. The most famous example is Phineas Gage, a railway worker, who in 1848 suffered extreme frontal lobe damage when a long iron rod was projected through his skull after an accidental explosion.
What activates the DLPFC?
Decision making. The DLPFC is involved in both risky and moral decision making; when individuals have to make moral decisions like how to distribute limited resources, the DLPFC is activated. This region is also active when costs and benefits of alternative choices are of interest.
How big is the DLPFC?
The mean ± SD DLPFC volumes were 9.23 ± 2.35 ml for the left hemisphere and 8.20 ± 2.08 ml for the right hemisphere.
