According to one interpretation, this brain region participates directly in the storage of information.
A central feature of this kind of behavioral flexibility is the ability to resolve conflicting response tendencies, suggesting a general role of the PFC in resolving interference. The exact workings of the brain have yet to be uncovered but imaging technology has led to increased knowledge of the processes involved in memory. The prefrontal cortex also houses active, working memory. Thank you for submitting your article "Retrieval practice facilitates memory updating by enhancing and differentiating medial prefrontal cortex representations" for consideration by eLife. The primate dorsolateral prefrontal cortex (DLPFC) has long been implicated in higher cognitive functions, such as switching attention, working memory, maintaining abstract rules, and inhibiting inappropriate responses. This study assesses the activity of the PFC in performing the Sternberg WM task (ST) with three levels of difficulty (easy, medium and hard) using the near-infrared spectroscopy (fNIRS) technique. DLPFC is not required for the memory of a single item. As such, a properly functioning prefrontal cortex inhibits inappropriate behaviors — including delaying gratification of needs, for things like food or sex — while encouraging wise, acceptable choices. How can all these roles be reconciled? Similarly, it may be hypothesized that left inferior prefrontal cortex is activated to the extent that semantic information must be held temporarily in working memory (in mind) to answer a particular semantic … Domain-specific working memory activations have been reported in right prefrontal cortex for spatial working memory tasks and in posterior left prefrontal cortex for phonological working memory tasks .
We provide an “executive-attention” framework for organizing the cognitive neuroscience research on the constructs of working-memory capacity (WMC), general fluid intelligence, and prefrontal cortex (PFC) function.
The role of medial prefrontal cortex in memory and decision making. The prefrontal cortex is an important site for working memory function. Since the PFC controls intense emotions and impulses, it is sometimes referred to as the seat of good judgment. Connections between the PFC and the hippocampus are particularly important for episodic memory. The prefrontal cortex (PFC) and hippocampus support complementary functions in episodic memory. Others suggest mPFC is selectively involved in the retrieval of remote long-term memory. Thus, damage to the dorsolateral prefrontal cortex does not impair recognition memory. [email protected] Some have claimed that the medial prefrontal cortex (mPFC) mediates decision making. In animal paradigms, the prefrontal cortex (PFC) has been shown to help facilitate pattern separation, and ultimately, attenuate memory interference. Connections between the PFC and the hippocampus are particularly important for episodic memory. Some have claimed that the medial prefrontal cortex (mPFC) mediates decision making. However, the PFC is also associated with control of working memory. Your article has been reviewed by two peer reviewers, and the evaluation has been overseen by a Reviewing Editor and Laura Colgin as the Senior Editor. The connection between the prefrontal cortex and memory arises as this part of the brain seems to play a key role in controlling working, or short-term, memory. The prefrontal cortex (PFC) is known to be critically involved in strategy switching, attentional set shifting, and inhibition of prepotent responses. Euston DR(1), Gruber AJ, McNaughton BL. The prefrontal cortex (PFC) and hippocampus support complementary functions in episodic memory. The Prefrontal cortex (PFC) has been highly related to executive functions such as working memory (WM).
Yet others suggests mPFC supports memory and consolidation on time scales ranging from seconds to days. Research evaluating the role of the PFC on memory interference among humans is, however, limited. We used scalp electroencephalography in groups of patients with unilateral PFC or …
The reviewers have opted to remain anonymous. Visual working memory (VWM) is a remarkable skill dependent on the brain's ability to construct and hold an internal representation of the world for later comparison with an external stimulus. The prefrontal cortex (PFC) and basal ganglia (BG) interact within a cortical and subcortical network supporting VWM.

Nevertheless, if two items must be compared from memory, the involvement of DLPFC is required.
