TL;DR: Comparison of sensitivity showed a general trend towards greater sensitivity to task manipulations by MVPA compared to univariate analysis, which demonstrates that MVPA methods may provide a different view of the functional organization of mental processing compared tounivariate analysis.

TL;DR: This work focuses on how the combination of study design and pattern estimator impacts the Type I error rate of the subsequent pattern analysis, and shows that collinearities in the models, along with temporal autocorrelation, can cause false positive correlations between activation pattern estimates that adversely impact the false positive rates of pattern similarity and classification analyses.

TL;DR: The presence of two distinct temporal states that fluctuated over the course of 18 mo were identified, associated with distinct patterns of time-resolved blood oxygen level dependent (BOLD) connectivity within individual scanning sessions and related to significant alterations in global efficiency of brain connectivity as well as differences in self-reported attention.

TL;DR: The MRI Quality Control tool (MRIQC), a tool for extracting quality measures and fitting a binary (accept/exclude) classifier, is introduced, which performs with high accuracy in intra-site prediction, but performance on unseen sites leaves space for improvement.

TL;DR: The Cognitive Atlas Project is outlined, which is developing formal ontologies that describe the structure of mental processes, and it is shown how this knowledge could be used in conjunction with data-mining approaches to more directly relate mental processes and brain function.
