What does the dorsolateral frontal cortex do?
What does the dorsolateral frontal cortex do?
The dorsolateral prefrontal cortex has been found to be involved in superordinate control functions for various cognitive tasks such as decision making, novelty detection, working memory, conflict management, mood regulation, theory of mind processing, and timing.
What happens when the dorsolateral prefrontal cortex is damaged?
Lesions of the dorsolateral PFC (DLPFC), consisting of Brodmann areas (BA) 9 and 46 in the human (Fig. 2, left), can result in deficits across a wide range of functions, including working memory, rule-learning, planning, attention, and motivation (Fig. 3).
Is the dorsolateral prefrontal cortex 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).
Where is the dorsolateral frontal cortex located?
The dlPFC is located on the lateral and dorsal part of the medial convexity of the frontal lobe and comprises BA 9 and 46 and a few transitional areas: 9-8, 9-45, 46-10, and 46-45 (for a detailed description of anatomical boundaries, see (Rajkowska and Goldman-Rakic, 1995b, a).
Where is the dorsolateral?
The dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the brain of humans and other primates. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts until adulthood.
What is frontal lobe syndrome?
Frontal lobe syndrome, in general, refers to a clinical syndrome resulting from damage, and impaired function of the prefrontal cortex, which is a large association area of the frontal lobe. The areas involved may include the anterior cingulate, the lateral prefrontal cortex, the orbitofrontal cortex, and the frontal poles.
What is a ventromedial orbitofrontal lesion?
Ventromedial Orbitofrontal Cortex Commonly known to cause “frontal lobe personality”, lesions in the orbitofrontal areas classically cause dramatic changes in behavior leading to impulsivity and a lack of judgment.
What are the symptoms of frontal lobe dysfunction (FLD)?
Symptoms of possible frontal lobe dysfunction that should be probed include change in performance at work and changes organizing and executing difficult tasks such as holiday dinners or travel itineraries 11). The examiner should inquire about the following changes:
Where is the frontal lobe located in the brain?
Neuroanatomically, the frontal lobe is the largest lobe of the brain lying in front of the central sulcus. It is divided into 3 major areas defined by their anatomy and function. They are the primary motor cortex, the supplemental and premotor cortex, and the prefrontal cortex. Damage to the primary …
