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
A developmental functional mri study of prefrontal activation during performance of a go-no-go task
B. J. Casey,Rolf J. Trainor,Jennifer L. Orendi,Anne B. Schubert,Leigh E. Nystrom,Jay N. Giedd,F. Xavier Castellanos,James V. Haxby,Douglas C. Noll,Jonathan D. Cohen,Steven D. Forman,Ronald E. Dahl,Judith L. Rapoport +12 more
TL;DR: Although inhibitory processes have typically been associated with more ventral or orbital frontal regions, the current study revealed activation that was distributed across both dorsolateral and orbitofrontal cortices, consistent with animal and human lesion studies.
Journal ArticleDOI
Dissociating working memory from task difficulty in human prefrontal cortex
M Deanna,Todd S. Braver,Leigh E. Nystrom,Steven D. Forman,Douglas C. Noll,Jonathan D. Cohen,Jonathan D. Cohen +6 more
TL;DR: A double-dissociation between regions responsive to WM versus task difficulty is established, indicating a specific involvement of DLPFC and related structures in WM function.
Journal ArticleDOI
Activation of the prefrontal cortex in a nonspatial working memory task with functional MRI
Jonathan D. Cohen,Steven D. Forman,Todd S. Braver,B. J. Casey,David Servan-Schreiber,David Servan-Schreiber,Douglas C. Noll,Douglas C. Noll +7 more
TL;DR: These findings corroborate the results of positron emission tomography studies, which suggest that the prefrontal cortex is engaged by tasks that rely on working memory, and demonstrate the applicability of newly developed fMRI techniques using conventional scanners to study the associative cortex in individual subjects.
Journal ArticleDOI
Opiate addicts lack error-dependent activation of rostral anterior cingulate.
Steven D. Forman,Steven D. Forman,George G Dougherty,George G Dougherty,B. J. Casey,B. J. Casey,Greg J. Siegle,Greg J. Siegle,Todd S. Braver,M Deanna,V. Andrew Stenger,Charlene Wick-Hull,Liubomir A. Pisarov,Emily Lorensen +13 more
TL;DR: The attenuation of this error signal in anterior cingulate cortex may play a role in loss of control in addiction and other forms of impulsive behavior.
