Retrieval of information from episodic memory involves the processes invoked by the attempt to remember (retrieval attempt) as well as processes associated with the successful retrieval of stored information (ecphory). Previous PET studies of memory have shown an activation of the prefrontal cortex in memory retrieval tasks, and we hypothesised that this activation represents retreival attempt, not ecphory. This hypothesis was directly directed using [15O]H2 PET imaging in 19 healthy subjects… Expand
Right prefrontal cortex and episodic memory retrieval: a functional MRI test of the monitoring hypothesis.
This functional MRI study of 12 healthy volunteers tested the hypothesis that one role of the right prefrontal cortex is to monitor the information retrieved from episodic memory in order to make an appropriate response. Expand
Memory retrieval and the parietal cortex: A review of evidence from a dual-process perspective
A meta-analysis of findings from event-related fMRI studies reporting the loci of retrieval effects associated with familiarity- and recollection-related recognition judgments supports suggestions that retrieval-related activity in lateral parietal cortex dissociates between superior regions, where activity likely reflects the task relevance of different classes of recognition test items.

The Role of Prefrontal Cortex in Verbal Episodic Memory: rTMS Evidence
The results indicate that the nature of the material to be remembered interacts with the encodingretrieval DLPFC asymmetry; moreover, the crucial role of DLP FC is evident only for novel stimuli. Expand
Memory retrieval under the control of the prefrontal cortex.
Findings suggest that the prefrontal cortex can regulate the recall of long-term memory in the absence of bottom-up sensory inputs. Expand
The role of prefrontal cortex during tests of episodic memory
The `cortical asymmetry of reflective activity' (CARA) hypothesis summarizes available findings and suggests directions for future research. Expand
Selective activation of the ventrolateral prefrontal cortex in the human brain during active retrieval processing
By strictly controlling the level of encoding, postretrieval monitoring, and decision making, the present study has demonstrated a specific increase in the ventrolateral prefrontal region that could be clearly related to active retrieval processing, i.e. the active selection of particular stored visual representations.

PET studies of encoding and retrieval: The HERA model
We review positron emission tomography (PET) studies whose results converge on the hemispheric encoding/retrieval asymmetry (HERA) model of the involvement of prefrontal cortical regions in theExpand
Prefrontal cortex and recognition memory. Functional-MRI evidence for context-dependent retrieval processes.
These experiments suggest that right prefrontal regions mediate processes associated with retrieval attempt, with the probability of engaging these regions depending upon the retrieval context. Expand
Functional network in the prefrontal cortex during episodic memory retrieval
Findings support the hypothesis of an associative contribution of the bilateral posterior PFC to episodic memory retrieval and a dissociative contribution to the bilateral anterior PFC. Expand
On the Relations among Priming, Conscious Recollection, and Intentional Retrieval: Evidence from Neuroimaging Research
Evidence indicating that priming, a form of implicit retrieval, is associated with decreased activity in various cortical regions is considered, as well as evidence suggesting that two components of explicit retrieval-intentional or effortful search and successful conscious recollection-are preferentially associated with increased activity in prefrontal and medial temporal regions.
