High-Fidelity Mapping of Repetition-Related Changes in the Parietal Memory Network
(Elsevier Inc., 2019-06-05)
fMRI studies of human memory have identified a “parietal memory network” (PMN) that displays distinct responses to novel and familiar stimuli, typically deactivating during initial encoding but robustly activating during ...
Are There Multiple Kinds of Episodic Memory? An fMRI Investigation Comparing Autobiographical and Recognition Memory Tasks
(Society for Neuroscience, 2018-08-20)
What brain regions underlie retrieval from episodic memory? The bulk of research addressing this question with fMRI has relied upon recognition memory for materials encoded within the laboratory. Another, less dominant ...
Transcranial Magnetic Stimulation of the Left Angular Gyrus During Encoding Does not Impair Associative Memory Performance
The left angular gyrus (AG) is thought to play a critical role in episodic retrieval and has been implicated in the recollection of specific details of prior episodes. Motivated by recent fMRI studies in which it was ...
ASL-MRICloud: An Online Tool for the Processing of ASL MRI Data
(Wiley, 2018-12-26)
Arterial spin labeling (ASL) MRI is increasingly used in research and clinical settings. The purpose of this work is to develop a cloud-based tool for ASL data processing, referred to as ASL-MRICloud, which may be useful ...
Shorter Term Aerobic Exercise Improves Brain, Cognition, and Cardiovascular Fitness in Aging
Physical exercise, particularly aerobic exercise, is documented as providing a low cost regimen to counter well-documented cognitive declines including memory, executive function, visuospatial skills, and processing speed ...
Automatic and Reproducible Positioning of Phase-Contrast MRI for the Quantification of Global Cerebral Blood Flow
Phase-Contrast MRI (PC-MRI) is a noninvasive technique to measure blood flow. In particular, global but highly quantitative cerebral blood flow (CBF) measurement using PC-MRI complements several other CBF mapping methods ...
Higher-Order Cognitive Training Effects on Processing Speed-Related Neural Activity: A Randomized Trial
Higher-order cognitive training has shown to enhance performance in older adults, but the neural mechanisms underlying performance enhancement have yet to be fully disambiguated. This randomized trial examined changes in ...
Relative Activation Patterns Associated with Self-Transcendent and Self-Enhancement Core Values: An fMRI Study of Basic Human Values Theory Concepts in Males
(Taylor and Francis Ltd., 2019-04-13)
Core values have been shown to influence a variety of social behaviors, but research on the brain networks supporting their effects is sparse. While undergoing fMRI scanning, twenty male participants evaluated descriptions ...
Three‐Dimensional Lesion Phenotyping and Physiologic Characterization Inform Remyelination Ability in Multiple Sclerosis
BACKGROUND AND PURPOSE Multiple sclerosis (MS) clinical management is based upon lesion characterization from 2‐dimensional (2D) magnetic resonance imaging (MRI) views. Such views fail to convey the lesion‐phenotype (ie, ...
Long-Term Effects of Marijuana Use on the Brain
Questions surrounding the effects of chronic marijuana use on brain structure continue to increase. To date, however, findings remain inconclusive. In this comprehensive study that aimed to characterize brain alterations ...
