Journal ArticleDOI
Shared Neural Mechanisms of Visual Perception and Imagery.
TL;DR: There is a large overlap in neural processing during perception and imagery: neural representations of imagined and perceived stimuli are similar in the visual, parietal, and frontal cortex, and perceptions and imagery seem to rely on similar top-down connectivity.
Journal ArticleDOI
The what, where and how of delay activity.
TL;DR: What delay activity is, where in the brain it is found, what roles it serves and how it may be generated is reconsiders.
Journal ArticleDOI
Neural mechanisms of attending to items in working memory.
TL;DR: Evidence suggests both sustained activity and synaptic plasticity support working memory and rapid Hebbian plasticity can support flexible attractor states analogous to a focus of attention.

Flexible Coding of Visual Working Memory Representations during Distraction
Elizabeth S. Lorenc,Kartik K. Sreenivasan,Derek Evan Nee,Derek Evan Nee,Annelinde R. E. Vandenbroucke,Annelinde R. E. Vandenbroucke,Mark D'Esposito,Mark D'Esposito +7 more
TL;DR: Quantitative model-based fMRI analyses are used to reconstruct the contents of working memory and examine the effects of distracting input, and suggest a dynamic tradeoff between visual and parietal regions that allows flexible adaptation to task demands in service of VWM.
Journal ArticleDOI
Reaffirming the Sensory Recruitment Account of Working Memory
TL;DR: Based on the current evidence, the traditional view that VWM recruits sensory processing areas for maintaining visual information available after termination of its sensory input should be reluctant to revise.

An integrative theory of prefrontal cortex function
Earl K. Miller,Jonathan D. Cohen +1 more
TL;DR: It is proposed that cognitive control stems from the active maintenance of patterns of activity in the prefrontal cortex that represent goals and the means to achieve them, which provide bias signals to other brain structures whose net effect is to guide the flow of activity along neural pathways that establish the proper mappings between inputs, internal states, and outputs needed to perform a given task.

The human brain is intrinsically organized into dynamic, anticorrelated functional networks
Michael D. Fox,Abraham Z. Snyder,Justin L. Vincent,Maurizio Corbetta,David C. Van Essen,Marcus E. Raichle +5 more
TL;DR: It is suggested that both task-driven neuronal responses and behavior are reflections of this dynamic, ongoing, functional organization of the brain, featuring the presence of anticorrelated networks in the absence of overt task performance.
Journal ArticleDOI
Neurophysiological investigation of the basis of the fMRI signal
TL;DR: These findings suggest that the BOLD contrast mechanism reflects the input and intracortical processing of a given area rather than its spiking output, and that LFPs yield a better estimate of BOLD responses than the multi-unit responses.
Journal ArticleDOI
The magical number 4 in short-term memory: a reconsideration of mental storage capacity.
TL;DR: A wide variety of data on capacity limits suggesting that the smaller capacity limit in short-term memory tasks is real is brought together and a capacity limit for the focus of attention is proposed.

TL;DR: In this article, the authors studied functional brain organization in healthy adults using resting state functional connectivity MRI and proposed two novel brain wide graphs, one of 264 putative functional areas, the other a modification of voxelwise networks that eliminates potentially artificial short-distance relationships.
