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 function of the dorsolateral prefrontal cortex?
Dorsolateral prefrontal cortex (DLPFC) has been found to be involved in cognitive functions such as
executive function, response selection, and working memory
.
What activates dorsolateral prefrontal cortex?
In healthy control subjects,
tasks involving executive functions, such as working memory, inhibition, or attentional switching
, typically activate prefrontal regions that overlap with those involved in processing and regulating emotion, including the medial prefrontal cortex (PFC) and orbitofrontal cortex, anterior …
What does the medical term dorsolateral mean?
Medical Definition of dorsolateral
:
of, relating to, or involving both the back and the sides the dorsolateral prefrontal cortex
. Other Words from dorsolateral. dorsolaterally -ē adverb.
What does the anterior prefrontal cortex do?
The anterior prefrontal cortex is known to
subserve higher cognitive functions such as task management and planning
. Less is known, however, about the functional specialization of this cortical region in humans.
What happens if 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).
What are the symptoms of frontal lobe damage?
- loss of movement, either partial (paresis) or complete (paralysis), on the opposite side of the body.
- difficulty performing tasks that require a sequence of movements.
- trouble with speech or language (aphasia)
- poor planning or organization.
How can I improve my dorsolateral prefrontal cortex?
- Games: Word games, memory games, and puzzles are effective ways to strengthen your prefrontal cortex. …
- Learning: Learning something new, like a language, instrument, or other skill, is even more effective than word games at enhancing your prefrontal cortex.
Where is the ventromedial prefrontal cortex?
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).
Where is the DLPFC located?
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).

At what age is the prefrontal cortex fully developed?
The development and maturation of the prefrontal cortex occurs primarily during adolescence and is fully accomplished at the age of
25 years
. The development of the prefrontal cortex is very important for complex behavioral performance, as this region of the brain helps accomplish executive brain functions.
What parts of the brain are in the prefrontal cortex?
Anatomical terms of neuroanatomy
In mammalian brain anatomy, the prefrontal cortex (PFC) is the cerebral cortex which
covers the front part of the frontal lobe
. The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47.
Does the prefrontal cortex control emotion?
The prefrontal cortex is
like a control center
, helping to guide our actions, and therefore, this area is also involved during emotion regulation. Both the amygdala and the prefrontal cortex are part of the emotion network.
