Journal ArticleDOI

Perfusion functional MRI reveals cerebral blood flow pattern under psychological stress

TL;DR: The results provide neuroimaging evidence that psychological stress induces negative emotion and vigilance and that the ventral RPFC plays a key role in the central stress response.
Journal ArticleDOI

Empirical optimization of ASL data analysis using an ASL data processing toolbox: ASLtbx.

TL;DR: It was found that CBF calculations should be performed prior to spatial normalization and that modeling of global fluctuations yielded significantly increased peak t value in motor cortex.
Journal ArticleDOI

Gender difference in neural response to psychological stress

TL;DR: This study used perfusion based functional magnetic resonance imaging to measure cerebral blood flow responses to mild to moderate stress in 32 healthy people and may represent an initial step in uncovering the neurobiological basis underlying the contrasting health consequences of psychosocial stress in men and women.
Journal ArticleDOI

Imaging Brain Fatigue from Sustained Mental Workload: An ASL Perfusion Study of the Time-On-Task Effect

TL;DR: Results demonstrate the persistent effects of cognitive fatigue in the fronto-parietal network after a period of heavy mental work and indicate the critical role of this attentional network in mediating time-on-task (TOT) effects.
Journal ArticleDOI

Neural correlates of voluntary and involuntary risk taking in the human brain: an fMRI Study of the Balloon Analog Risk Task (BART).

TL;DR: These findings demonstrate the utility of the modified BART paradigms for using during fMRI to assess risk taking in the human brain, and suggest that recruitment of the brain mesolimbic-frontal pathway during risk-taking is contingent upon the agency of the risk taker.
