Conceptual Processing during the Conscious Resting State: A Functional MRI Study
TLDR
A model that proposes that perceptual tasks interrupt processes ongoing during rest that involve many of the same brain areas engaged during semantic retrieval may help to explain several unanticipated results from prior studies of semantic processing.
Development of a multiple sclerosis functional composite as a clinical trial outcome measure.
TLDR
A composite measure encompassing the major clinical dimensions of arm, leg and cognitive function was identified and termed the multiple sclerosis functional composite (MSFC), suggesting that the MSFC is more sensitive to change than the EDSS.
Distributed Neural Systems Underlying the Timing of Movements
TLDR
The results suggest that the internal generation of precisely timed movements is dependent on three interrelated neural systems, one that is involved in explicit timing (putamen, ventrolateral thalamus, SMA), one that mediates auditory sensory memory (IFG, STG), and another that is involvement in sensorimotor processing (dorsal dentate nucleus, sensorim motor cortex).
Determination of language dominance using functional MRI
TLDR
Functional MRI testing in 22 consecutive epilepsy patients undergoing intracarotid amobarbital testing and compared language lateralization measures obtained with the two procedures validate the FMRI technique and suggest that ``active'' areas observed with this semantic processing task correspond to those underlying hemispheric dominance for language.
Functional magnetic resonance imaging of complex human movements
TLDR
Six right-handed healthy subjects were scanned while they performed self-paced simple and complex finger movements with the right and left hands, and preliminary results are consistent with hierarchical models of voluntary motor control.
Can medial temporal lobe regions distinguish true from false? An event-related functional MRI study of veridical and illusory recognition memory
TLDR
The results suggest that activity in anterior MTL regions does not distinguish True from False, whereas activity in posterior M TL regions does.

TLDR
The view that affective disturbance may also result from cerebral demyelination is presented, along with a brief discussion of MS as a prototype "subcortical" dementia and methodological problems intrinsic to the study of MS.
Relationship between Finger Movement Rate and Functional Magnetic Resonance Signal Change in Human Primary Motor Cortex
TLDR
Results of this study indicated a positive linear relationship between movement rate and FMRI signal change and the number of voxels demonstrating functional activity increased significantly with faster movement rates.
The development, standardization, and initial validation of the Chicago Multiscale Depression Inventory.
TLDR
This study presents the Chicago Multiscale Depression Inventory (CMDI), a factorially derived self-report depression scale that includes Mood, Evaluative, and Vegetative subscales, and shows the CMDI and each of its subscales to be internally consistent, reliable, and valid.
Nicotine-induced limbic cortical activation in the human brain: a functional MRI study.
TLDR
Functional magnetic resonance imaging revealed that nicotine induced a dose-dependent increase in several behavioral parameters, including feelings of "rush" and "high" and drug liking, suggesting that nicotine acts similarly in the human brain to produce its reinforcing and dependence properties.
