Neural Activation During Response Competition
TL;DR: This study measured brain activity using functional magnetic resonance imaging (fMRI) during performance of the flanker task to suggest that the frontal foci may be related to response inhibition processes whereas the posterior foci is related to the activation of representations of the inappropriate responses.

TL;DR: The results suggest that an approach which uses the average of all available sessions, all trials of each session, and excludes outliers based on predetermined lenient criteria yields reliable SSRT estimates, while not excluding too many participants.
Journal ArticleDOI
Automatic independent component labeling for artifact removal in fMRI.

TL;DR: It is concluded that automatic ICA-based denoising offers a potentially useful approach to improve the quality of fMRI data and consequently increase the accuracy of the statistical analysis of these data.
Journal ArticleDOI
Progress and challenges in probing the human brain
TL;DR: Current methods in human neuroscience are highlighted, highlighting the ways that they have been used to study the neural bases of the human mind and the prospects for real-world applications and new scientific challenges for human neuroscience.
Journal ArticleDOI
The role of fMRI in Cognitive Neuroscience: where do we stand?
TL;DR: Some of the limits on the kinds of inferences that can be supported by fMRI are outlined, focusing particularly on reverse inference, in which the engagement of specific mental processes is inferred from patterns of brain activation.
