The Role of Left Ventrolateral Prefrontal Cortex during Episodic Decisions: Semantic Elaboration or Resolution of Episodic Interference?
Context memory retrieval tasks often implicate the left ventrolateral pFC (LVPFC) during functional imaging. Although this region has been linked to controlled semantic processing of materials, it may also play a more general role in selecting among competing episodic representations during demanding retrieval tasks. Thus, the LVPFC response during context memory retrieval may reflect either se...
متن کاملSemantic retrieval, mnemonic control, and prefrontal cortex.
Accessing stored knowledge is a fundamental function of the cognitive and neural architectures of memory. Here, the authors review evidence from cognitive-behavioral paradigms, neuropsychological studies of patients with focal neural insult, and functional brain imaging concerning the mechanisms underlying retrieval of semantic knowledge and their association with prefrontal cortex. First, the ...
متن کاملLeft ventrolateral prefrontal cortex and the cognitive control of memory.
Cognitive control mechanisms permit memory to be accessed strategically, and so aid in bringing knowledge to mind that is relevant to current goals and actions. In this review, we consider the contribution of left ventrolateral prefrontal cortex (VLPFC) to the cognitive control of memory. Reviewed evidence supports a two-process model of mnemonic control, supported by a double dissociation amon...
متن کاملPrefrontal cortex and episodic memory retrieval mode.
A multistudy analysis of positron emission tomography data identified three right prefrontal and two left prefrontal cortical sites, as well as a region in the anterior cingulate gyrus, where neuronal activity is correlated with the maintenance of episodic memory retrieval mode (REMO), a basic and necessary condition of remembering past experiences. The right prefrontal sites were near the fron...
متن کاملOrganization of cortico-cortical pathways supporting memory retrieval across subregions of the left ventrolateral prefrontal cortex.
Functional magnetic resonance imaging (fMRI) evidence indicates that different subregions of ventrolateral prefrontal cortex (VLPFC) participate in distinct cortical networks. These networks have been shown to support separable cognitive functions: anterior VLPFC [inferior frontal gyrus (IFG) pars orbitalis] functionally correlates with a ventral fronto-temporal network associated with top-down...
