Combining temporal and spatial constraints in task-based fMRI

open access: yes, 2022
Constrained principal component analysis for fMRI (fMRI-CPCA) is carried out in two main steps: (1) blood-oxygen-level dependent (BOLD) signal is row (time)-constrained to variance predictable from a finite impulse response (FIR) model, and (2) task ...

Preoperative mapping of the sensorimotor cortex: comparative assessment of task-based and resting-state FMRI. [PDF]

open access: yesPLoS ONE, 2014
Resting state fMRI (rs-fMRI) has recently been considered as a possible complement or alternative to task-based fMRI (tb-fMRI) for presurgical mapping.

Prediction of task-related BOLD fMRI with amplitude signatures of resting-state fMRI [PDF]

open access: yesFrontiers in Systems Neuroscience, 2012
We explored task-activated fMRI (T-fMRI) signals and their relationship to the resting state fMRI (R-fMRI) signals based on the hypothesis that they arise from a common hemodynamic substrate.

Cognitive Modes Detectable with Task-Based fMRI

open access: yes
Functional magnetic resonance imaging (fMRI) is a non-invasive neuroimaging technique, primarily utilized to map the spatiotemporal distribution and patterns of underlying brain activity. Since its invention 30 years ago, fMRI has had remarkable academic

Cognitive Mode Detectable with Task-Based fMRI: Initiation (INIT)

open access: yes
In the context of task-based functional magnetic resonance imaging (fMRI), cognitive modes can be defined as task-general cognitive/sensory/motor processes which reliably elicit specific blood-oxygen-level-dependent (BOLD) signal pattern configurations ...

Connectivity analyses for task-based fMRI. [PDF]

open access: yesPhys Life Rev
Functional connectivity is conventionally defined by measuring the similarity between brain signals from two regions. The technique has become widely adopted in the analysis of functional magnetic resonance imaging (fMRI) data, where it has provided cognitive neuroscientists with abundant information on how brain regions interact to support complex ...
