Capacity limit of visual short-term memory in human posterior parietal cortex
TLDR
Functional magnetic resonance imaging is used to suggest that activity in the posterior parietal cortex is tightly correlated with the limited amount of scene information that can be stored in visual short-term memory, and suggests that the posterior PAR cortex is a key neural locus of the authors' impoverished mental representation of the visual world.

The role of the fusiform face area in social cognition: implications for the pathobiology of autism.
TLDR
In two linked functional magnetic resonance imaging studies of healthy young adults, it is shown that the FFA is engaged by a social attribution task (SAT) involving perception of human-like interactions among three simple geometric shapes. Expand
A central role for the lateral prefrontal cortex in goal-directed and stimulus-driven attention
TLDR
It is found that the ventral, but not dorsal, network can account for stimulus-driven attentional limits to conscious perception, and that stimulus- driven and goal-directed attention converge in the lateral prefrontal component of that network. Expand
Isolation of a Central Bottleneck of Information Processing with Time-Resolved fMRI
TLDR
Using time-resolved functional magnetic resonance imaging, fMRI results suggest that a neural network of frontal lobe areas acts as a central bottleneck of information processing that severely limits the authors' ability to multitask. Expand
The Neural Fate of Consciously Perceived and Missed Events in the Attentional Blink
TLDR
The results suggest that medial temporal cortex permits rapid categorization of the visual input, while the frontal cortex is part of a capacity-limited attentional bottleneck to conscious report. Expand
Capacity limits of information processing in the brain
TLDR
A review of the neurobiological literature suggests that the capacity limit of VSTM storage is primarily localized to the posterior parietal and occipital cortex, whereas the AB and PRP are associated with partly overlapping fronto-parietal networks. Expand

TLDR
The individual-differences approach supports a key role for the PPC in VSTM by demonstrating that its activity level predicts individual differences in V STM storage capacity. Expand
Visual Short-Term Memory Load Suppresses Temporo-Parietal Junction Activity and Induces Inattentional Blindness
TLDR
It is demonstrated that as the visual short-term memory (VSTM) load of a task increases, activity in the right temporo-parietal junction is increasingly suppressed, and a plausible neural mechanism for this perceptual deficit is offered: suppression of the stimulus-driven attentional network. Expand
fMRI Evidence for a Dual Process Account of the Speed-Accuracy Tradeoff in Decision-Making
TLDR
These findings suggest that the SAT is neurally implemented by modulating not only the amount of externally-derived sensory evidence used to make a decision, but also the internal urge to makea response, which combines to control the temporal dynamics of the speed-accuracy trade-off in decision-making. Expand
The attentional blink: A review of data and theory

  • 1 November 2009
TLDR
It is concluded that the attentional blink arises from attentional demands of Tl for selection, working memory encoding, episodic registration, and response selection, which prevents this high-level central resource from being applied to T2 at shortT1-T2 lags. Expand
