What is the dorsolateral region?
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 dorsolateral cortex responsible for?
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 is the function of the dorsolateral prefrontal cortex?
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 does the middle frontal gyrus do?
[4] Inferior to the superior frontal gyrus, and separated from it by the superior frontal sulcus, is the middle frontal gyrus. The dominant (left) middle frontal gyrus plays a key role in the development of literacy, while the nondominant (right) middle frontal gyrus is responsible for numeracy.
What are the symptoms associated with a lesion in a dorsolateral prefrontal cortex?
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 happens if the middle frontal gyrus is damaged?
What might be the role of dorsolateral prefrontal areas lying on the middle and superior frontal gyrus in language? Damage to these areas yields severe impairments in certain aspects of working memory and in attention control, but there are no obvious impairments in language production or comprehension.
Where is the middle frontal gyrus located?
the frontal lobe
The middle frontal gyrus is part of the superolateral surface of the frontal lobe, located between the superior frontal sulcus and inferior frontal sulcus, which respectively separate it from the superior frontal gyrus and inferior frontal gyrus.
What weakens the prefrontal cortex?
The higher cognitive functions of the recently evolved prefrontal cortex (PFC) are weakened with exposure to stress, reducing top-down regulation and switching control of behavior to more primitive brain circuits.
What is the function of the middle frontal gyrus?
The right middle fontal gyrus (MFG) has been proposed to be a site of convergence of the dorsal and ventral attention networks, by serving as a circuit-breaker to interrupt ongoing endogenous attentional processes in the dorsal network and reorient attention to an exogenous stimulus.
What is the middle frontal gyrus responsible for?
The dominant (left) middle frontal gyrus plays a key role in the development of literacy, while the nondominant (right) middle frontal gyrus is responsible for numeracy. [5] Within the caudal portion of the middle frontal gyrus, at the intersection with the precentral gyrus, is the frontal eye fields (Brodmann area 8).
What is the role of the medial frontal gyrus?
Some have claimed that the medial prefrontal cortex (mPFC) mediates decision making. Others suggest mPFC is selectively involved in the retrieval of remote long-term memory. Yet others suggests mPFC supports memory and consolidation on time-scales ranging from seconds to days.
What happens to the prefrontal cortex in anxiety?
In primates, anxiety can be regulated by the prefrontal cortex (PFC), which has expanded in evolution. This prefrontal expansion is thought to underlie primates’ increased capacity to engage high-level regulatory strategies aimed at coping with and modifying the experience of anxiety.
What does the middle temporal gyrus do?
The middle temporal gyrus and inferior temporal gyrus subserve language and semantic memory processing, visual perception, and multimodal sensory integration. Functional deficits in these cognitive processes have been well documented in patients with schizophrenia.
