In humans, the anterior insula (aI) has been the topic of considerable research and ascribed a vast number of functional properties by way of neuroimaging and lesion studies. Here, we argue that the aI, at least in part, plays a role in domain-general attentional control and highlight studies (Dosenbach et al. 2006; Dosenbach et al. 2007) supporting this view. Additionally, we discuss a study (Plo...<br/><br/>Steven M Nelson, Nico U F Dosenbach, Alexander L Cohen, Mark E Wheeler, Bradley L Schlaggar, Steven E Petersen (2010) <i>Brain Struct Funct</i> <i></i> <i></i> 214: 5-6 669-680<br/>

The parietal lobe has long been viewed as a collection of architectonic and functional subdivisions. Though much parietal research has focused on mechanisms of visuospatial attention and control-related processes, more recent functional neuroimaging studies of memory retrieval have reported greater activity in left lateral parietal cortex (LLPC) when items are correctly identified as previously st...<br/><br/>Steven M Nelson, Alexander L Cohen, Jonathan D Power, Gagan S Wig, Francis M Miezin, Mark E Wheeler, Katerina Velanova, David I Donaldson, Jeffrey S Phillips, Bradley L Schlaggar, Steven E Petersen (2010) <i>Neuron</i> <i></i> <i></i> 67: 1 156-170<br/>

Studies in non-human primates and humans reveal that discrete regions (henceforth, "divisions") in the basal ganglia are intricately interconnected with regions in the cerebral cortex. However, divisions within basal ganglia nuclei (e.g., within the caudate) are difficult to identify using structural MRI. Resting-state functional connectivity MRI (rs-fcMRI) can be used to identify putative cerebra...<br/><br/>Kelly Anne Barnes, Alexander L Cohen, Jonathan D Power, Steven M Nelson, Yannic B L Dosenbach, Francis M Miezin, Steven E Petersen, Bradley L Schlaggar (2010) <i>Front Syst Neurosci</i> <i></i> <i></i> 4: <br/>

Group functional connectivity magnetic resonance imaging (fcMRI) studies have documented reliable changes in human functional brain maturity over development. Here we show that support vector machine-based multivariate pattern analysis extracts sufficient information from fcMRI data to make accurate predictions about individuals' brain maturity across development. The use of only 5 minutes of rest...<br/><br/>Nico U F Dosenbach, Binyam Nardos, Alexander L Cohen, Damien A Fair, Jonathan D Power, Jessica A Church, Steven M Nelson, Gagan S Wig, Alecia C Vogel, Christina N Lessov-Schlaggar, Kelly Anne Barnes, Joseph W Dubis, Eric Feczko, Rebecca S Coalson, John R Pruett, Deanna M Barch, Steven E Petersen, Bradley L Schlaggar (2010) <i>Science</i> <i></i> <i></i> 329: 5997 1358-1361<br/>

The mature human brain is organized into a collection of specialized functional networks that flexibly interact to support various cognitive functions. Studies of development often attempt to identify the organizing principles that guide the maturation of these functional networks. In this report, we combine resting state functional connectivity MRI (rs-fcMRI), graph analysis, community detection,...<br/><br/>Damien A Fair, Alexander L Cohen, Jonathan D Power, Nico U F Dosenbach, Jessica A Church, Francis M Miezin, Bradley L Schlaggar, Steven E Petersen (2009) <i>PLoS Comput Biol</i> <i></i> <i></i> 5: 5 <br/>

Diffuse optical tomography (DOT) is a portable functional neuroimaging technique that is able to simultaneously measure both oxy- and deoxyhemoglobin responses to brain activity. Herein, we demonstrate a technique for mapping functional connections in the brain by measuring the spatial distribution of temporal correlations in resting brain activity.

Mapping resting-state networks allows insight into the brain's functional architecture and physiology and has rapidly become important in contemporary neuroscience research. Diffuse optical tomography (DOT) is an emerging functional neuroimaging technique with the advantages, relative to functional magnetic resonance imaging (fMRI), of portability and the ability to simultaneously measure both oxy...<br/><br/>Brian R White, Abraham Z Snyder, Alexander L Cohen, Steven E Petersen, Marcus E Raichle, Bradley L Schlaggar, Joseph P Culver (2009) <i>Neuroimage</i> <i></i> <i></i> 47: 1 148-156<br/>

Tourette syndrome (TS) is a developmental disorder characterized by unwanted, repetitive behaviours that manifest as stereotyped movements and vocalizations called 'tics'. Operating under the hypothesis that the brain's control systems may be impaired in TS, we measured resting-state functional connectivity MRI (rs-fcMRI) between 39 previously defined putative control regions in 33 adolescents wit...<br/><br/>Jessica A Church, Damien A Fair, Nico U F Dosenbach, Alexander L Cohen, Francis M Miezin, Steven E Petersen, Bradley L Schlaggar (2009) <i>Brain</i> <i></i> <i></i> 132: Pt 1 225-238<br/>

In recent years, the brain's "default network," a set of regions characterized by decreased neural activity during goal-oriented tasks, has generated a significant amount of interest, as well as controversy. Much of the discussion has focused on the relationship of these regions to a "default mode" of brain function. In early studies, investigators suggested that, the brain's default mode supports...<br/><br/>Damien A Fair, Alexander L Cohen, Nico U F Dosenbach, Jessica A Church, Francis M Miezin, Deanna M Barch, Marcus E Raichle, Steven E Petersen, Bradley L Schlaggar (2008) <i>Proc Natl Acad Sci U S A</i> <i></i> <i></i> 105: 10 4028-4032<br/>

Complex systems ensure resilience through multiple controllers acting at rapid and slower timescales. The need for efficient information flow through complex systems encourages small-world network structures. On the basis of these principles, a group of regions associated with top-down control was examined. Functional magnetic resonance imaging showed that each region had a specific combination of...<br/><br/>Nico U F Dosenbach, Damien A Fair, Alexander L Cohen, Bradley L Schlaggar, Steven E Petersen (2008) <i>Trends Cogn Sci</i> <i></i> <i></i> 12: 3 99-105<br/>

The cerebral cortex is anatomically organized at many physical scales starting at the level of single neurons and extending up to functional systems. Current functional magnetic resonance imaging (fMRI) studies often focus at the level of areas, networks, and systems. Except in restricted domains, (e.g., topographically-organized sensory regions), it is difficult to determine area boundaries in th...<br/><br/>Alexander L Cohen, Damien A Fair, Nico U F Dosenbach, Francis M Miezin, Donna Dierker, David C Van Essen, Bradley L Schlaggar, Steven E Petersen (2008) <i>Neuroimage</i> <i></i> <i></i> 41: 1 45-57<br/>

Resting state functional connectivity MRI (fcMRI) has become a particularly useful tool for studying regional relationships in typical and atypical populations. Because many investigators have already obtained large data sets of task-related fMRI, the ability to use this existing task data for resting state fcMRI is of considerable interest.

Control regions in the brain are thought to provide signals that configure the brain's moment-to-moment information processing. Previously, we identified regions that carried signals related to task-control initiation, maintenance, and adjustment. Here we characterize the interactions of these regions by applying graph theory to resting state functional connectivity MRI data. In contrast to previo...<br/><br/>Nico U F Dosenbach, Damien A Fair, Francis M Miezin, Alexander L Cohen, Kristin K Wenger, Ronny A T Dosenbach, Michael D Fox, Abraham Z Snyder, Justin L Vincent, Marcus E Raichle, Bradley L Schlaggar, Steven E Petersen (2007) <i>Proc Natl Acad Sci U S A</i> <i></i> <i></i> 104: 26 11073-11078<br/>

Human attentional control is unrivaled. We recently proposed that adults depend on distinct frontoparietal and cinguloopercular networks for adaptive online task control versus more stable set control, respectively. During development, both experience-dependent evoked activity and spontaneous waves of synchronized cortical activity are thought to support the formation and maintenance of neural net...<br/><br/>Damien A Fair, Nico U F Dosenbach, Jessica A Church, Alexander L Cohen, Shefali Brahmbhatt, Francis M Miezin, Deanna M Barch, Marcus E Raichle, Steven E Petersen, Bradley L Schlaggar (2007) <i>Proc Natl Acad Sci U S A</i> <i></i> <i></i> 104: 33 13507-13512<br/>

alpha-Dystrobrevin (DB), a cytoplasmic component of the dystrophin-glycoprotein complex, is found throughout the sarcolemma of muscle cells. Mice lacking alphaDB exhibit muscular dystrophy, defects in maturation of neuromuscular junctions (NMJs) and, as shown here, abnormal myotendinous junctions (MTJs). In normal muscle, alternative splicing produces two main alphaDB isoforms, alphaDB1 and alphaD...<br/><br/>R Mark Grady, Mohammed Akaaboune, Alexander L Cohen, Margaret M Maimone, Jeff W Lichtman, Joshua R Sanes (2003) <i>J Cell Biol</i> <i></i> <i></i> 160: 5 741-752<br/>
