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. WebThe present study examined the relative contributions of the prefrontal cortex (PFC) and posterior parietal cortex (PPC) to visual working memory. Evidence from a number of different techniques has led to the theory that the PFC controls access to working memory (i.e., filtering), determining which information is encoded and maintained for later use …
Prefrontal Cortex and Working Memory SpringerLink
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 … WebApr 24, 2024 · Neural substrates of working memory in the prefrontal cortex. Early studies of working memory in monkeys employed the DR task to examine the dlPFC cellular contributions to this cognitive domain. It was discovered that during the delay period a subset of pyramidal cells in area 46 of the dlPFC is persistently active (Fuster and … halcyonminds tech llp

WebApr 12, 2024 · Morphology and function of the dorsolateral prefrontal cortex (dlPFC), and corresponding working memory performance, are affected early in the aging process, but nearly half of aged individuals are spared of working memory deficits. Translationally relevant model systems are critical for determining the neurobiological drivers of this … WebApr 5, 2024 · It is revealed that WM load makes learning slower and decisions noisier in an instrumental learning task with Pavlovian components, and FMRI analysis revealed that the WM load weakens the functional connectivity between the prefrontal cortex and the striatum when people anticipate outcomes before making a decision.
