Journal ArticleDOI
TL;DR: White matter-specific atlases in stereotaxic coordinates are introduced and showed a high correlation between the manual ROI-based and the automated approaches for normal adult populations.

1,521 citations


Journal ArticleDOI
TL;DR: This study created a white matter parcellation atlas based on probabilistic maps of 11 major white matter tracts derived from the DTI data from 28 normal subjects, and automated tract-specific quantification of fractional anisotropy and mean diffusivity were performed.

1,350 citations


Journal ArticleDOI
TL;DR: Differences observed in developmental timing suggest a pattern of maturation in which areas with fronto-temporal connections develop more slowly than other regions, which is consistent with previous postmortem and imaging studies.

1,293 citations



Journal ArticleDOI
TL;DR: This work quantified the negative correlation between these two networks in 26 subjects, during active (Eriksen flanker task) and resting state scans, and found that the strength of the correlation between the two networks varies across individuals.

1,204 citations


Journal ArticleDOI
TL;DR: This study assessed functional connectivity within the default mode network during both rest and a continuous working memory task on a region-by-region basis using partial correlation analysis, a data-driven method that provides insight into effective connectivity within neuronal networks.

1,097 citations


Journal ArticleDOI
TL;DR: The pRF method is non-invasive and can be applied to a wide range of conditions when it is useful to link fMRI signals in the visual pathways to neuronal receptive fields, and the visual field maps obtained are more accurate than those obtained using conventional visual field mapping.

Journal ArticleDOI
TL;DR: The construction of a digital brain atlas composed of data from manually delineated MRI data, providing a resource for automated probabilistic labeling of external data types registered into standard spaces, and computed average intensity images and tissue density maps based on the three methods and target spaces.

1,011 citations


Journal ArticleDOI
TL;DR: Results suggest that medial frontal areas are more closely associated with core limbic activation than their lateral counterparts, and that dmPFC may play a particularly important role in the cognitive generation of emotional states.

1,003 citations


Journal ArticleDOI
TL;DR: Findings indicate that DSI tractography is able to image crossing fibers in neural tissue, an essential step toward non-invasive imaging of connectional neuroanatomy.

Journal ArticleDOI
TL;DR: A novel approach for quantifying functional connectivity among brain networks identified with spatial ICA is presented and applied to functional magnetic resonance imaging (fMRI) data collected from persons with schizophrenia and healthy controls.

Journal ArticleDOI
TL;DR: Compared to normal-weight controls, obese women exhibited greater activation in response to pictures of high-calorie foods in a large number of regions hypothesized to mediate motivational effects of food cues.

Journal ArticleDOI
TL;DR: The results are interpreted as evidence for a highly efficient organization of the functionally connected brain, in which voxels are mostly connected with their direct neighbors forming clustered sub-networks, which are held together by a small number of highly connected hub-voxels that ensure a high level of overall connectivity.

Journal ArticleDOI
TL;DR: The key contribution is the automatic selection of multiple cortical sources with compact spatial support that are specified in terms of empirical priors that obviates the need to use priors with a specific form (e.g., smoothness or minimum norm).

Journal ArticleDOI
TL;DR: A new "respiration response function" consists of an early overshoot followed by a later undershoot (peaking at approximately 16 s), and accurately models the MRI signal changes resulting from breath-holding as well as cued depth and rate changes.

Journal ArticleDOI
TL;DR: An experimental model of crossing fibres, consisting of water-filled plastic capillaries, is used to thoroughly assess three such techniques: constrained spherical deconvolution (CSD), super-resolved CSD (super-CSD) and Q-ball imaging (QBI).

Journal ArticleDOI
TL;DR: The neural substrates underlying auditory feedback control of speech were investigated using a combination of functional magnetic resonance imaging (fMRI) and computational modeling, revealing increased activity in bilateral superior temporal cortex during shifted feedback and increased influence of bilateral auditory cortical areas on right frontal areas during shifted speech.

Journal ArticleDOI
TL;DR: It is found that rs-fcMRI patterns show sharp transitions in correlation patterns and that these putative areal boundaries can be reliably detected in individual subjects as well as in group data, and combining surface-based analysis techniques with image processing algorithms allows automated mapping of putativeAreal boundaries across large expanses of cortex.

Journal ArticleDOI
TL;DR: Recursive Feature Elimination is evaluated in terms of sensitivity of discriminative maps (Receiver Operative Characteristic analysis) and generalization performances and compare it to previously used univariate voxel selection strategies based on activation and discrimination measures.

Journal ArticleDOI
TL;DR: By taking Thierry et al.'s study as an exemplar case of what should not be done in ERP research of visual categorization processes, clarifications are provided on a number of methodological and theoretical issues about the N170 and its largest amplitude to faces.

Journal ArticleDOI
TL;DR: Since acquisition time is the same for MEMPR as for MPRAGE, and it has better distortion properties and additional T2* information, MEMPR is recommended for morphometry studies.

Journal ArticleDOI
TL;DR: Assessment of the relationship between dopamine D2 receptor availability in striatum with brain glucose metabolism in obese subjects and controls suggested that decreases in striatal D2 receptors could contribute to overeating via their modulation of striatal prefrontal pathways, which participate in inhibitory control and salience attribution.

Journal ArticleDOI
TL;DR: In a vulnerability and betweenness centrality analysis, the most indispensable and critical anatomical areas were identified: putamens, precuneus, insulas, superior parietals and superior frontals, which suggest that even at the cost of losing in global anatomical efficiency, these structures were maintained through the evolutionary processes due to their important functions.

Journal ArticleDOI
TL;DR: A set of guidelines for the reporting of methods and results in functional magnetic resonance imaging studies are outlined and a checklist to assist authors in preparing manuscripts that meet these guidelines are provided.

Journal ArticleDOI
TL;DR: This work proposes a group inference approach which includes inference of outliers using a robust general linear model (GLM) approach which combines the benefits of outlier inference with thebenefits of using variance information from lower levels in the hierarchy.

Journal ArticleDOI
TL;DR: This work used axonal fiber alignment information from diffusion tensor imaging (DTI) to delineate the peripheral white matter, and investigated its relationship with the cortex and the deep white matter.

Journal ArticleDOI
TL;DR: Using resting functional connectivity MRI (fcMRI), it is found that, in autism, there was altered functional organization of the network involved in social and emotional processing, but no group difference in the functional organizations of thenetwork involved in sustained attention and goal-directed cognition.

Journal ArticleDOI
TL;DR: Direct comparison between functional RSTC and anatomical DTI connectivity, presented here for the first time, links two powerful approaches for investigating brain connectivity and shows their strong agreement.

Journal ArticleDOI
TL;DR: High-dimensional pattern classification, a nonlinear multivariate analysis, provided measures of structural abnormality that can potentially be useful for individual patient classification, as well as for predicting progression and examining multivariate relationships in group analyses.

Journal ArticleDOI
TL;DR: A three-dimensional atlas of the mouse brain, manually segmented into 62 structures, based on an average of 32 mum isotropic resolution T(2)-weighted, within skull images of forty 12 week old C57Bl/6J mice, scanned on a 7 T scanner is described.
