Activated cliques: Network-based activation detection in task-based FMRI
2013 IEEE 10th International Symposium on Biomedical Imaging, 2013Human brain function has been widely believed as a network behavior. However, most previous activation detection methods in the task-based fMRI field were voxel-based, instead of network-based. For instance, the general linear model (GLM) has been widely used to fit the external stimulus curve with the fMRI BOLD signal of each voxel.

Activated Fibers: Fiber-Centered Activation Detection in Task-Based FMRI
2011In task-based fMRI, the generalized linear model (GLM) is widely used to detect activated brain regions. A fundamental assumption in the GLM model for fMRI activation detection is that the brain's response, represented by the blood-oxygenation level dependent (BOLD) signals of volumetric voxels, follows the shape of stimulus paradigm.

Task-based functional connectivity of the Useful Field of View (UFOV) fMRI task
GeroScience, 2022Declines in processing speed performance occur in aging and are a critical marker of functional independence in older adults. Numerous studies suggest that Useful Field of View (UFOV) training may ameliorate cognitive decline in older adults. Despite its efficacy, little is known about the neural correlates of this task.

Exploring emotion regulation in PTSD with Insomnia: A task-based fMRI study
Journal of Psychiatric ResearchSleep disturbances and difficulties in emotion regulation are core symptoms of post-traumatic stress disorder (PTSD) and are closely related. However, the neural mechanisms underlying this relationship remain underexplored. To address this gap, we used task-based functional magnetic resonance imaging (fMRI) to examine brain mechanisms related to ...

Motor inhibition in functional paralysis – a task-based fMRI study
ISMRM Annual MeetingMotivation: In functional neurological disorders (FND), symptoms (including paralysis) occur despite intact anatomical pathways. The pathophysiology of FND is poorly understood, making diagnosis, treatment and prognosis uncertain. Goal(s): Assuming that higher cognitive functions may play a role in the manifestation of symptoms, this study investigates
