Statistical Improvements in Functional Magnetic Resonance Imaging Analyses Produced by Censoring High-Motion Data Points
Joshua S. Siegel,Jonathan D. Power,Joseph W. Dubis,Alecia C. Vogel,Jessica A. Church,Bradley L. Schlaggar,Steven E. Petersen +6 more
TL;DR: It is concluded that motion censoring improves the quality of task fMRI data and can be a valuable processing step in studies involving populations with even mild amounts of head movement.
Object naming and action-verb generation in Parkinson's disease: a fMRI study.
Patrice Péran,Dominique Cardebat,Andrea Cherubini,Fabrizio Piras,Giacomo Luccichenti,Antonella Peppe,Carlo Caltagirone,Olivier Rascol,Jean-François Démonet,Umberto Sabatini +9 more
TL;DR: The results point to a relationship between motor system dysfunction in PD and the extent of activation in verb generation, a task which implies in-depth processing of semantic representation of actions.

Regional changes in word-production laterality after a naming treatment designed to produce a rightward shift in frontal activity.
Bruce Crosson,Anna Bacon Moore,Keith M. McGregor,Yu-Ling Chang,Michelle Benjamin,Kaundinya S. Gopinath,Megan E. Sherod,Christina E. Wierenga,Kyung K. Peck,Richard W. Briggs,Leslie J. Gonzalez Rothi,Keith D. White +11 more
TL;DR: Five nonfluent aphasia patients participated in a picture-naming treatment that used an intention manipulation to initiate naming trials and was designed to re-lateralize word production mechanisms from the left to the right frontal lobe, suggesting increasing efficiency of cortical processing as a result of treatment.

An fMRI Study of the Differences in Brain Activity During Active Ankle Dorsiflexion and Plantarflexion
Jonathan Trinastic,Steven A. Kautz,Keith M. McGregor,Keith M. McGregor,Chris M. Gregory,Mark G. Bowden,Michelle Benjamin,Michelle Benjamin,Marc Kurtzman,Yu-Ling Chang,Tim Conway,Tim Conway,Bruce Crosson,Bruce Crosson +13 more
TL;DR: Results suggest that ankle dorsiflexion and plantarflexion may be controlled by both shared and independent neural circuitry, which has important implications for functional investigations of gait pathology and how rehabilitation may differentially affect each movement.

Neuroimaging in aphasia treatment research: consensus and practical guidelines for data analysis.
Marcus Meinzer,Marcus Meinzer,Pélagie M. Beeson,Stefano F. Cappa,Jenny Crinion,Swathi Kiran,Dorothee Saur,Todd B. Parrish,Bruce Crosson,Cynthia K. Thompson +9 more
TL;DR: In this article, the authors provide a critical review of unique problems related to the pre-processing, statistical modeling and interpretation of such data sets, and discuss and communicate a basic set of practical guidelines that should be applicable to a wide range of studies and useful as a reference for researchers pursuing this line of research.

Spatial registration and normalization of images
Karl J. Friston,John Ashburner,Chris D. Frith,Jean-Baptiste Poline,Jon D. Heather,Richard S. J. Frackowiak +5 more
TL;DR: A general technique that facilitates nonlinear spatial (stereotactic) normalization and image realignment is presented that minimizes the sum of squares between two images following non linear spatial deformations and transformations of the voxel (intensity) values.

Movement-related effects in fMRI time-series
TL;DR: The empirical analyses suggest that (in extreme situations) over 90% of fMRI signal can be attributed to movement, and that this artifactual component can be successfully removed.
