Improved Assessment of Significant Activation in Functional Magnetic Resonance Imaging (fMRI): Use of a Cluster‐Size Threshold
TLDR
Monte Carlo simulations and fMRI studies of human subjects have been used to verify that this approach can improve statistical power by as much as fivefold over techniques that rely solely on adjusting per pixel false positive probabilities. Expand
A Predictive Approach to Model Selection
Abstract This article offers a synthesis of Bayesian and sample-reuse approaches to the problem of high structure model selection geared to prediction. Similar methods are used for low structureExpand
Brain Activation Modulated by Sentence Comprehension
TLDR
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. Expand
Maturation of Widely Distributed Brain Function Subserves Cognitive Development
TLDR
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. Expand
Combining Brains: A Survey of Methods for Statistical Pooling of Information
TLDR
Some popular methods for combining information are reviewed, the question of thresholding is critical here and is also explored; the surveyed techniques on a sample data set are demonstrated. Expand
Graded Functional Activation in the Visuospatial System with the Amount of Task Demand
TLDR
The data suggest that the amount of activation in the various cortical regions that support visuospatial processing is related to the amount, as well as to the type, of computational demand. Expand
Optimum Kernel Estimators of the Mode
FUNCTIONAL BRAIN ABNORMALITIES ARE RELATED TO CLINICAL RECOVERY AND TIME TO RETURN‐TO‐PLAY IN ATHLETES
TLDR
This study found that abnormal fMRI results during the first week of recovery predicted clinical recovery, and athletes who demonstrated hyperactivation on fMRI scans at the time of their first fMRI scan demonstrated a more prolonged clinical recovery. Expand
Time Course of fMRI-Activation in Language and Spatial Networks during Sentence Comprehension
TLDR
Evidence of differential amounts of brain activity related to high-level cognition (sentence processing) within 1.5 s of stimulus onset and the effect of negation indicates that the activation in these areas is modulated by the difficulty of the linguistic processing are suggested. Expand
Functional Imaging Analysis Software — Computational Olio
Magnetic resonance imaging (MRI) is a modern technique for producing pictures of the internals of the human body. An MR scanner subjects its contents to carefully modulated electro-magnetic fieldsExpand
