Journal ArticleDOI
Improved assessment of significant activation in functional magnetic resonance imaging (fMRI) : use of a cluster-size threshold
Steven D. Forman,Jonathan D. Cohen,Mark Fitzgerald,William F. Eddy,Mark A. Mintun,Douglas C. Noll +5 more
TL;DR: In this article, an alternative approach, which relies on the assumption that areas of true neural activity will tend to stimulate signal changes over contiguous pixels, is presented, which can improve statistical power by as much as fivefold over techniques that rely solely on adjusting per pixel false positive probabilities.
Journal ArticleDOI
Brain Activation Modulated by Sentence Comprehension
TL;DR: The comprehension of visually presented sentences produces brain activation that increases with the linguistic complexity of the sentence, and the amount of neural activity that a given cognitive process engenders is dependent on the computational demand that the task imposes.
Journal ArticleDOI
A Predictive Approach to Model Selection
Seymour Geisser,William F. Eddy +1 more
TL;DR: In this article, a synthesis of Bayesian and sample-reuse approaches to the problem of high structure model selection geared to prediction is presented. But this approach is not suitable for high-dimensional models.
Journal ArticleDOI
Maturation of widely distributed brain function subserves cognitive development.
Beatriz Luna,Keith R. Thulborn,Douglas P. Munoz,Elisha P. Merriam,Krista E. Garver,Nancy J. Minshew,Matcheri S. Keshavan,Christopher R. Genovese,William F. Eddy,John A. Sweeney +9 more
TL;DR: It is suggested that efficient top-down modulation of reflexive acts may not be fully developed until adulthood and evidence that maturation of function across widely distributed brain regions lays the groundwork for enhanced voluntary control of behavior during cognitive development is provided.
Journal ArticleDOI
Neocortical system abnormalities in autism: An fMRI study of spatial working memory
Beatriz Luna,Nancy J. Minshew,Krista E. Garver,Nicole A. Lazar,Keith R. Thulborn,William F. Eddy,John A. Sweeney +6 more
TL;DR: Impairments in executive cognitive processes in autism may be subserved by abnormalities in neocortical circuitry as evidenced by decreased activation in prefrontal and posterior cingulate circuitry during a spatial working memory task.
