What does the dorsolateral prefrontal cortex control?
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 are dorsolateral prefrontal cortex and frontal lobe are responsible for?
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 motor function does the dorsolateral prefrontal cortex DLPFC carry out?
3 Dorsolateral Prefrontal Cortex. The DLPFC sends afferent projections to the dorsal striatum (ie, the caudate and the putamen) and is involved in higher order processes, such as conscious decision making, reasoning, working memory, inhibition, as well as outcome prediction (Krawczyk, 2002).
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.
What does dorsolateral mean?
: of, relating to, or involving both the back and the sides.
What causes prefrontal cortex damage?
The cause of frontal lobe disorders includes an array of diseases ranging from closed head trauma (that may cause orbitofrontal cortex damage) to cerebrovascular disease, tumors compressing the frontal lobe, and neurodegenerative disease.
What are the effects of damage to the prefrontal cortex?
A person with damage to the prefrontal cortex might have blunted emotional responses, for instance. They might even become more aggressive and irritable, and struggle to initiate activities. Finally, they might perform poorly on tasks that require long-term planning and impulse inhibition.
What is the function of the ventromedial and ventrolateral hypothalamus?
The ventromedial nucleus of the hypothalamus (VMH) is important in the regulation of female sexual behavior, feeding, energy balance, and cardiovascular function. It is a highly conserved nucleus across species and a good model for studying neuronal organization into nuclei.
What are the anatomical terms for the dorsolateral prefrontal cortex?
Anatomical terms of neuroanatomy. The dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the brain of humans and non-human primates.
Is the dorsal medial prefrontal cortex involved in decision making?
The dmPFC is involved in decision-making, and drug addicts have difficulty in decision-making, frequently choosing drug-seeking and drug-using behavior despite the known negative consequences of those choices. Dysfunction in the dmPFC and its outputs would, therefore, be expected as a consequence on chronic drug abuse.
Is the dorsolateral prefrontal cortex estrogen sensitive?
The dorsolateral prefrontal cortex (dlPFC) and hippocampus are estrogen-sensitive brain regions that mediate complex cognitive function. This cognition is thought to require an increase in spine number (Elston, 2003).
Which is a key node of the dorsal cognitive circuit?
The DLPFC is a key node of the dorsal cognitive circuit (Figure 2 (c)). The DLPFC is involved in executive functioning and control of cognitive processes. Several studies have reported reduced DLPFC volumes in OCD. One study identified a correlation between increasing OCD severity and decreasing bilateral DLPFC volume.
