FBNETGEN: Task-aware GNN-based fMRI Analysis via Functional Brain Network Generation
International Conference on Medical Imaging with Deep Learning, 2022Functional magnetic resonance imaging (fMRI) is one of the most common imaging modalities to investigate brain functions. Recent studies in neuroscience stress the great potential of functional brain networks constructed from fMRI data for clinical ...

International Anesthesiology Clinics, 2016
BOLD activation studies discussed vary in the anesthetic agent studied (propofol, sevoflurane, and isoflurane), the concentration of the anesthetic (mostly under 0.5MAC or equivalent doses), and the activation paradigm/functional activation. The data analysis technique also differs between the studies.

Data quality in fMRI and simultaneous EEG–fMRI
Magnetic Resonance Materials in Physics, Biology and Medicine, 2014To evaluate functional magnetic resonance imaging (fMRI) and simultaneous electroencephalography (EEG)-fMRI data quality in an organization using several magnetic resonance imaging (MRI) systems.Functional magnetic resonance imaging measurements were carried out twice with a uniform gel phantom on five different MRI systems with field strengths of 1.5 ...

Movement‐Related effects in fMRI time‐series
Magnetic Resonance in Medicine, 1996This paper concerns the spatial and intensity transformations that are required to adjust for the confounding effects of subject movement during functional MRI (fMRI) activation studies. An approach is presented that models, and removes, movement‐related

, 2006 This review concentrates on functional MRI (fMRI) methods to identify the epileptic focus; i.e., ictal and interictal fMRI. First, established clinical applications of fMRI in the field of epilepsy are briefly introduced: fMRI of sensorimotor, language, and memory functions can be considered already as clinically relevant tools to identify eloquent ...

The field of pain research has progressed immensely due to the advancement of brain imaging techniques. The initial goal of this research was to expand our understanding of the cerebral mechanisms underlying the perception of pain; more recently the research objectives have shifted toward chronic pain – understanding its origins, developing methods for

Simultaneous EEG and fMRI Recordings (EEG-fMRI)
2013Scalp EEG is characterised by a limited spatial resolution and by a low sensitivity to generators distant from the cortical surface. In contrast, fMRI is characterised by a good spatial resolution and it is sensitive to signal of deep brain structures. By combining EEG with fMRI, it is possible to detect blood oxygenation level-dependent (BOLD) signal ...

Recent brain imaging work has expanded our understanding of the mechanisms of perceptual, cognitive, and motor functions in human subjects, but research into the cerebral control of emotional and motivational function is at a much earlier stage. Important concepts and theories of emotion are briefly introduced, as are research designs and multimodal ...

AIP Conference Proceedings, 2004
Localization of eloquent areas is of utmost importance in neurosurgical planning, especially in epilepsy surgery. Mass, destructive, or developmental lesions may distort brain anatomy. Functional MRI (fMRI) can localize eloquent areas despite these distortions and provide useful information for the planning of tailored resections. This paper deals with
