Language task-based fMRI analysis using machine learning and deep learning [PDF]

Frontiers in Radiology
IntroductionTask-based language fMRI is a non-invasive method of identifying brain regions subserving language that is used to plan neurosurgical resections which potentially encroach on eloquent regions.

Task fMRI paradigms may capture more behaviorally relevant information than resting-state functional connectivity

NeuroImage, 2023
Characterizing the optimal fMRI paradigms for detecting behaviorally relevant functional connectivity (FC) patterns is a critical step to furthering our knowledge of the neural basis of behavior.

An information-theoretic analysis of resting-state versus task fMRI

Network Neuroscience, 2023
Resting-state fMRI is an increasingly popular alternative to task-based fMRI. However, a formal quantification of the amount of information provided by resting-state fMRI as opposed to active task conditions about neural responses is lacking.

Brain effective connectivity and functional connectivity as markers of lifespan vascular exposures in middle-aged adults: The Bogalusa Heart Study

Frontiers in Aging Neuroscience, 2023
IntroductionEffective connectivity (EC), the causal influence that functional activity in a source brain location exerts over functional activity in a target brain location, has the potential to provide different information about brain network dynamics ...

Mapping language function with task-based vs. resting-state functional MRI.

PLoS ONE, 2020
BackgroundUse of functional MRI (fMRI) in pre-surgical planning is a non-invasive method for pre-operative functional mapping for patients with brain tumors, especially tumors located near eloquent cortex.

Integration of resting state functional MRI into clinical practice - A large single institution experience.

PLoS ONE, 2018
Functional magnetic resonance imaging (fMRI) is an important tool for pre-surgical evaluation of eloquent cortex. Classic task-based paradigms require patient participation and individual imaging sequence acquisitions for each functional domain that is ...
