One model of the functional organization of lateral prefrontal cortex (PFC) in primates posits that this region is organized in a dorsal/ventral fashion subserving spatial and object working memory, respectively. Alternatively, it has been proposed that a dorsal/ventral subdivision of lateral PFC instead reflects the type of processing performed upon information held in working memory. We tested this hypothesis using an event-related fMRI method that can discriminate among functional changes… 
The role of lateral prefrontal cortex in working memory: evidence from event-related fMRI studies
Abstract Working memory refers to the short-term storage of information that is not accessible in the environment, and the set of processes that keep this information accessible for maintenance and
Prefrontal cortical contributions to working memory: evidence from event-related fMRI studies
TLDR
Data from a series of event-related functional magnetic-resonance-imaging studies of delayed-response tasks that were designed to investigate the role of different regions of the prefrontal cortex during different working-memory component processes conclude that lateral PFC is anatomically organized according to the types of cognitive operations one performs when attempting to temporarily maintain and manipulate information.
Maintenance and Manipulation in Spatial Working Memory: Dissociations in the Prefrontal Cortex
TLDR
Claims that the dorsolateral prefrontal cortex is involved in the manipulation of internal representa tions and that the superior frontal sulcal region is involvement in the maintenance of spatial information but they suggest a complex role for the ventrolatera prefrontal region are suggested.
Direct Comparison of Prefrontal Cortex Regions Engaged by Working and Long-Term Memory Tasks
TLDR
The results highlight the importance of examining PFC activity across multiple memory domains, both for functionally differentiating PFC regions (e.g., task-selectivity vs material- selectivity in DL-P FC and VL-PFC) and for testing the applicability of memory domain-specific theories (e-g., FP- PFC in LTM retrieval).
Evidence for multiple manipulation processes in prefrontal cortex
TLDR
The results suggest that (1) the neural substrates associated with long-list retention and those associated with reordering are not equivalent, (2) cognitive processes associated withLong- list retention may be more closely approximated by item-order maintenance than by reordering, and (3) multiple forms of WM manipulation are dissociable on the basis of fMRI data.
Maintenance and Manipulation in Working Memory : Differential Ventral and Dorsal Frontal Cortex fMRI Activity
A verbal working memory protocol was designed and evaluated on a group of healthy younger adults in preparation for a large-scale functional magnetic resonance (fMRI) study on aging and memory.
Maintenance versus manipulation in verbal working memory revisited: an fMRI study
TLDR
The data support a functional rather than a neuroanatomical distinction between maintenance and manipulation, given the finding that these tasks differentially activate virtually identical systems.
Models of Functional Organization of the Lateral Prefrontal Cortex in Verbal Working Memory: Evidence in Favor of the Process Model
TLDR
This study directly compared process-related versus material-related organizational principles in a verbal working memory task and found evidence during the delay period of the task to support claims of anterior-posterior specializations in the ventrolateral PFC for semantic versus phonological processing.
Binding of What and Where During Working Memory Maintenance
TLDR
A model is presented, extending the principles of "biased competition" to the PFC and the dynamic maintenance of information in WM, that accounts for current and seemingly contradictory previous results from both imaging and physiological studies.
WhatThenWhere in Visual Working Memory: An Event-Related fMRI Study

"What"-Then-Where" in visual working memory: an event-related fMRI study.
TLDR
This experiment failed to find evidence, at the single-subject level and at the group level, for anatomical segregation of spatial and object working memory function in the frontal cortex, and investigated the neural bases of this dissociation with a whole-brain fMRI design and analysis technique.

TLDR
It was observed that dorsal PFC plays a differentially greater role in information retrieval for slower subjects, possibly because of inefficient retrieval processes or a reduced quality of mnemonic representations.
Functional MRI studies of spatial and nonspatial working memory.
TLDR
An analysis of all reported human functional neuroimaging studies plotted onto a standardized brain found no evidence for a dorsal/ventral subdivision of prefrontal cortex depending on the type of material held in working memory, but a hemispheric organization was suggested (i.e., left-nonspatial; right-spatial).
Temporal isolation of the neural correlates of spatial mnemonic processing with fMRI.
TLDR
Functional changes attributable to the memory requiring phase of a spatial working memory task were temporally discriminated from those attributable to other behavioral subcomponents within trials using an experimental design argued to obviate these assumptions, as well as permit a joint test of their validity.
The neural substrate and temporal dynamics of interference effects in working memory as revealed by event-related functional MRI.
TLDR
Using event-related functional MRI, spatially and temporally a proactive interference effect is characterized that may reflect the operation of a PFC-mediated response-inhibition mechanism that contributes to working memory performance.
Dissociating working memory from task difficulty in human prefrontal cortex
TLDR
A double-dissociation between regions responsive to WM versus task difficulty is established, indicating a specific involvement of DLPFC and related structures in WM function.

TLDR
The ability of monkeys with IC lesions to perform visual pattern association tasks and color-matching tasks, both with and without delay are assessed.

TLDR
It is possible that the combination of cue and delay activity with post-trial activity constitutes the neuronal basis for the two areas' differences in behavioral function.
Evidence for a two-stage model of spatial working memory processing within the lateral frontal cortex: a positron emission tomography study.
TLDR
P positron emission tomography with magnetic resonance imaging is used to demonstrate the existence of two functionally distinct subdivisions of the lateral frontal cortex, which may subserve different aspects of spatial working memory.
Bilateral activation of fronto-parietal networks by incrementing demand in a working memory task.
TLDR
The increased demand during alternated matching resulted in bilateral activation of both dorsolateral prefrontal and inferior parietal cortex, which has previously been coactivated with the prefrontal cortex in several WM tasks, irrespective of the sensory modality of the stimuli.
