Spontaneous fluctuations in brain activity observed with functional magnetic resonance imaging

MD Fox, ME Raichle - Nature reviews neuroscience, 2007 - nature.com
The majority of functional neuroscience studies have focused on the brain's response to a
task or stimulus. However, the brain is very active even in the absence of explicit input or …

The reorienting system of the human brain: from environment to theory of mind

M Corbetta, G Patel, GL Shulman - Neuron, 2008 - cell.com
Survival can depend on the ability to change a current course of action to respond to
potentially advantageous or threatening stimuli. This" reorienting" response involves the …

Persistent activity in the prefrontal cortex during working memory

CE Curtis, M D'Esposito - Trends in cognitive sciences, 2003 - cell.com
The dorsolateral prefrontal cortex (DLPFC) plays a crucial role in working memory. Notably,
persistent activity in the DLPFC is often observed during the retention interval of delayed …

Capacity limit of visual short-term memory in human posterior parietal cortex

JJ Todd, R Marois - Nature, 2004 - nature.com
At any instant, our visual system allows us to perceive a rich and detailed visual world. Yet
our internal, explicit representation of this visual world is extremely sparse: we can only hold …

Increased prefrontal and parietal activity after training of working memory

PJ Olesen, H Westerberg, T Klingberg - Nature neuroscience, 2004 - nature.com
Working memory capacity has traditionally been thought to be constant. Recent studies,
however, suggest that working memory can be improved by training. In this study, we have …

Decoding reveals the contents of visual working memory in early visual areas

SA Harrison, F Tong - Nature, 2009 - nature.com
Visual working memory provides an essential link between perception and higher cognitive
functions, allowing for the active maintenance of information about stimuli no longer in view …

Competition between functional brain networks mediates behavioral variability

AMC Kelly, LQ Uddin, BB Biswal, FX Castellanos… - Neuroimage, 2008 - Elsevier
Increased intraindividual variability (IIV) is a hallmark of disorders of attention. Recent work
has linked these disorders to abnormalities in a “default mode” network, comprising brain …

Working memory as an emergent property of the mind and brain

BR Postle - Neuroscience, 2006 - Elsevier
Cognitive neuroscience research on working memory has been largely motivated by a
standard model that arose from the melding of psychological theory with neuroscience data …
