The causal role of right dorsolateral prefrontal cortex in visual working memory

The present study confirmed the causal role of the right DLPFC in representing the visual working memory information during the retrieval period.

The impact of age on load-related dorsolateral prefrontal cortex activation

The present findings argue for an increasing functional cerebral dysfunction over a time span of 50 years that may partly be compensated on the behavioral level until a resource ceiling is approached.

Are ventrolateral and dorsolateral prefrontal cortices involved in the computerized Corsi block-tapping test execution? An fNIRS study

The results of the Bayesian analysis have not shown a delineated specific activation of VLPFC/DLPFC during either CBTs or CBTb, and results together with the related ones obtained by others using fMRI are not sufficient to definitively state the role of the PFC subregions during CBT execution.

Brain hemodynamic response in Examiner–Examinee dyads during spatial short-term memory task: an fNIRS study

Data support a bell-shaped relationship between cognitive load and brain activity, and provide original insights on the cognitive processes activated in the examiner during CBT.



Regional brain activity during working memory tasks.

The data confirm that the lower left supramarginal gyrus and premotor area are the key regions subserving short-term verbal memory processes and suggest that the updating memory task is related to middorsolateral prefrontal activation, most probably responsible for the updating function of the central executive.

The neural basis of the central executive system of working memory

Using functional magnetic resonance imaging to examine brain activation during the concurrent performance of two tasks, which is expected to engage the CES, results support the view that the prefrontal cortex is involved in human working memory.

Brain imaging of the central executive component of working memory

Neuroimaging studies of working memory:

A potential fourth executive function is considered: selective attention to features of a stimulus to be stored in WM which leads to increased probability of activating the medial prefrontal cortex (BA 32) in storage tasks.

Active maintenance in prefrontal area 46 creates distractor-resistant memory

It is proposed that memory representations gain resistance against distraction during a period of active maintenance within working memory, which may be mediated by interactions between prefrontal and posterior areas.

Dissociating executive functions of the prefrontal cortex.

Patients with frontal damage are shown to have deficits in their use of strategies to improve performance in a spatial working memory task and capacity to make an extra-dimensional shift due to a high-order failure of inhibition in an attentional set-shifting paradigm.

Functional neuroanatomical double dissociation of mnemonic and executive control processes contributing to working memory performance.

Data from event-related functional MRI investigate the neural bases of two categories of mental processes believed to contribute to performance of an alphabetization working memory task: memory storage and memory manipulation to support the view that working memory is a faculty that arises from the coordinated interaction of computationally and neuroanatomically dissociable processes.

Maintenance versus Manipulation of Information Held in Working Memory: An Event-Related fMRI Study

In each subject, activity during the delay period was found in both dorsolateral and ventrolateral PFC in both types of trials, however, dorsal/ventral PFC activity was greater in manipulation trials, consistent with the processing model of the functional organization of working memory in PFC.
