Showing papers in "NeuroImage in 2002"

TL;DR: An anatomical parcellation of the spatially normalized single-subject high-resolution T1 volume provided by the Montreal Neurological Institute was performed and it is believed that this tool is an improvement for the macroscopical labeling of activated area compared to labeling assessed using the Talairach atlas brain.

TL;DR: This paper introduces to the neuroscience literature statistical procedures for controlling the false discovery rate (FDR) and demonstrates this approach using both simulations and functional magnetic resonance imaging data from two simple experiments.

TL;DR: A critical comparison of findings across individual studies is provided and suggests that separate brain regions are involved in different aspects of emotion.

TL;DR: A toolbox called MarsBar is implemented for region of interest analysis within the SPM99 software package, which may have many advantages in terms of statistical power and the ease of interpretation of neuroimaging data.

TL;DR: The use of magnetic resonance diffusion tensor imaging to quantify the effect of dysmyelination on water directional diffusivities in brains of shiverer mice in vivo suggests that changes in lambda(perpendicular) and lambda(parallel) may potentially be used to differentiate myelin loss versus axonal injury.

TL;DR: Improvements to this method are described, and an extension of SIENA is extended to a new method for cross-sectional (single time point) analysis, which provides easy manual review of their output by the automatic production of summary images.

TL;DR: The results suggest that low- performing older adults recruited a similar network as young adults but used it inefficiently, whereas high-performing older adults counteracted age-related neural decline through a plastic reorganization of neurocognitive networks.

TL;DR: The use of diffusion tensor magnetic resonance tractography to visualize the three-dimensional structure of the major white matter fasciculi within living human brain adds a new dimension to anatomical descriptions of the living humanbrain.

TL;DR: A novel approach for combining published neuroimaging results from multiple studies, designed to maximize the quantification of interstudy concordance while minimizing the subjective aspects of meta-analysis is described.

TL;DR: In this article, the amplitude correspondences between NIRS and functional magnetic resonance imaging (fMRI) data have been investigated and strong correlations were found between fMRI changes and all optical measures, with oxyhemoglobin providing the strongest correlation.

TL;DR: The authors employed event-related fMRI and EEG data to investigate the biological basis of cognitive control of behavior using a GO/NOGO task optimized to produce response inhibitions, frequent commission errors, and the opportunity for subsequent behavioral correction.

TL;DR: Results suggest that the human amygdala shows a stronger response to affective facial expressions than to scenes, a bias that should be considered in the design of experimental paradigms interested in probing amygdala function.

TL;DR: It is suggested that the anterior insula is concerned with the integration of all the concordant multimodal sensory signals associated with voluntary movements, and the inferior parietal cortex represents movements in an allocentric coding system that can be applied to the actions of others as well as the self.

TL;DR: A new diagnostic indicator of FDG PET scan abnormality, based on age-adjusted t statistics and an automated voxel-based procedure, is presented and validated in a large data set comprising 110 normal controls and 395 patients with probable Alzheimer's disease (AD) that were studied in eight participating centers as discussed by the authors.

TL;DR: A series of models that exemplify the diversity of problems that can be addressed within the empirical Bayesian framework are presented, using PET data to show how priors can be derived from the between-voxel distribution of activations over the brain.

TL;DR: It is proposed that field maps with acceptable noise levels can be generated easily using a dual echo-time EPI sequence and the importance of distortion correction for anatomical coregistration, even for small distortions is demonstrated.

TL;DR: The procedures used in conventional data analysis are formulated in terms of hierarchical linear models and a connection between classical inference and parametric empirical Bayes (PEB) through covariance component estimation is established through covariances component estimation.

TL;DR: A new methodology for the measurement of the neural substrates of human social interaction is described, which allows for the performance of human behavioral experiments in which participants can interact with each other while functional MRI is acquired in synchrony with the behavioral interactions.

TL;DR: A study that investigates the neural substrates of "on-line" mentalizing, using PET, by asking volunteers to second-guess an opponent, suggesting a specific link between activity in this brain region and the adoption of an intentional stance.

TL;DR: Data suggest that Stroop task-related functional development of the parietal lobe occurs by adolescence, in contrast to prefrontal cortex function contributing to the Stroop interference task, which continues to develop into adulthood.

TL;DR: It is found that frontal, temporal, and parietal white Matter volumes, as well as frontal and temporal gray matter volumes, changed at significantly slower rates in autism patients than in controls across the 2- to 11-year-age range.

TL;DR: Although the level of SMA and cingulate cortex activation did not differ significantly between movement conditions, the timing of the hemodynamic response within the pre-SMA was significantly earlier for self-initiated compared with externally triggered movements, which clearly reflects involvement of the SMA in early processes associated with the preparation for voluntary movement.

TL;DR: ERP differences revealed that the magnitude of this repetition effect was smaller for negative and inverted than upright faces at 0-lag but not at 1-lag condition, suggesting face encoding and recognition processes were affected by inversion and contrast-reversal differently.

TL;DR: There is no simple correlation between these measures, except that low values of functional connectivity were not found together with high values of anatomical connectivity, and pairs of regions situated around the central sulcus indicated a dependence of the two connectivity measures on each other.

TL;DR: In this article, the authors presented normative microstate data for resting EEG obtained from a database of 496 subjects between the age of 6 and 80 years, which showed a lawful, complex evolution with age.

TL;DR: The present fMRI-data reveal that the human brain employs this neuronal network also for the processing of musical information, suggesting that the cortical network known to support language processing is less domain-specific than previously believed.

TL;DR: The results suggest that the right fronto-opercular cortex is part of the neural network generating the MMN, and that small deviants were hardly detected under fMRI conditions.

TL;DR: Findings support the idea that parietal cortex is involved in activating possible responses on the basis of learned stimulus-response associations, and that prefrontal cortex is recruited when there is a need to select between competing responses.

TL;DR: Direct cross-function comparisons are critical to understand the role of different brain regions in various cognitive functions and suggest that indexing operations mediated by the medial temporal lobes apply to both long-term and short-term memory traces.
