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.About:

Network hubs in the human brain
TL;DR: Combining data from numerous empirical and computational studies, network approaches strongly suggest that brain hubs play important roles in information integration underpinning numerous aspects of complex cognitive function.
Journal ArticleDOI
Experimental and Theoretical Approaches to Conscious Processing
TL;DR: Converging neuroimaging and neurophysiological data point to objective neural measures of conscious access: late amplification of relevant sensory activity, long-distance cortico-cortical synchronization at beta and gamma frequencies, and "ignition" of a large-scale prefronto-parietal network.

Conscious, preconscious, and subliminal processing: a testable taxonomy.
Stanislas Dehaene,Jean-Pierre Changeux,Jean-Pierre Changeux,Lionel Naccache,Jérôme Sackur,Claire Sergent +5 more
TL;DR: A taxonomy is proposed that distinguishes between vigilance and access to conscious report, as well as between subliminal, preconscious and conscious processing, and that conscious perception is systematically associated with surges of parieto-frontal activity causing top-down amplification.

Cognitive control in media multitaskers.
TL;DR: Results demonstrate that media multitasking, a rapidly growing societal trend, is associated with a distinct approach to fundamental information processing, with heavy media multitaskers more susceptible to interference from irrelevant environmental stimuli and from irrelevant representations in memory.
Journal ArticleDOI
A taxonomy of external and internal attention.
TL;DR: A taxonomy based on the types of information that attention operates over--the targets of attention is proposed, providing an organizing framework that recasts classic debates, raises new issues, and frames understanding of neural mechanisms.

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 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.

The capacity of visual working memory for features and conjunctions
Steven J. Luck,Edward K. Vogel +1 more
TL;DR: It is demonstrated that it is possible to retain information about only four colours or orientations in visual working memory at one time, but it is also possible to retaining both the colour and the orientation of four objects, indicating that visual workingMemory stores integrated objects rather than individual features.

Dual-task interference in simple tasks: Data and theory.
TL;DR: These conclusions challenge widely accepted ideas about attentional resources and probe reaction time methodologies and suggest new ways of thinking about continuous dual-task performance, effects of extraneous stimulation, and automaticity.
