Prefrontal cortex and working memory
WebJan 28, 2024 · Author summary We found that oscillations in the prefrontal cortex form “traveling waves”. Traveling waves are spatially extended patterns in which aligned peaks of activity move sequentially across the cortical surface. Some traveling waves were planar but most rotated. The prefrontal cortex is important for working memory. The traveling … WebApr 11, 2024 · Because working memory deficits have been well-established in the rodent MK801 model, we used this aspect of cognition to probe the capacity of our prefrontal excitatory PV-DREADD approach to ...

WebIt proposes how laminar circuits of lateral prefrontal cortex carry out working memory storage of event sequences within layers 6 and 4, how these event sequences are unitized through learning into list chunks within layer 2/3, and how these stored sequences can be recalled at variable rates that are under volitional control by the basal ganglia.
WebApr 10, 2024 · Social exclusion has been found to impair working memory (WM). However, the emotional mechanism underlying this adverse effect remains unclear. Besides, little is known about how to alleviate this adverse effect. In the current study, 128 participants were randomly assigned to a social excluded group or an included group while they received … WebAbstract The prefrontal cortex has long been suspected to play an important role in cognitive control, in the ability to orchestrate thought and action in accordance with internal goals. Its neural basis, however, has remained a mystery. Here, we propose that cognitive control stems from the active maintenance of patterns of activity in the prefrontal cortex …
WebThe aim of this review is to present the main findings that have emerged from experiments which used the TMS technique for memory analysis. They mainly focused on the role of the dorsolateral prefrontal cortex in memory process. Furthermore, we present state-of-the-art evidence supporting a possible use of TMS in the clinic. WebAuthor(s): Soyuhos, Orhan; Baldauf, Daniel Abstract: Neuroimaging evidence suggests that the frontal eye field (FEF) and inferior frontal junction (IFJ) govern the encoding of spatial and nonspatial (such as feature- or object-based) representations, respectively, both during visual attention and working memory tasks. However, it is still unclear whether such …
