Reciprocal Benefits of Mass-Univariate and Multivariate Modeling in Brain Mapping: Applications to Event-Related Functional MRI, H215O-, and FDG-PET
MRI H215O FDG-PET
2009/9/8
In brain mapping studies of sensory, cognitive, and motor operations, specific waveforms of dynamic neural activity are predicted based on theoretical models of human information processing. For examp...
Magnetic Field Distribution and Signal Decay in Functional MRI in Very High Fields (up to 9.4 T) Using Monte Carlo Diffusion Modeling
Functional MRI Diffusion Modeling
2009/9/7
Extravascular signal decay rate R2 or R2∗ as a function of blood oxygenation, geometry, and field strength was calculated using a Monte Carlo (MC) algorithm for a wider parameter range than hith...
A Feature-Selective Independent Component Analysis Method for Functional MRI
Feature-Selective Independent Component Functional MRI
2009/9/7
In this work, we propose a simple and effective scheme to incorporate prior knowledge about the sources of interest (SOIs) in independent component analysis (ICA) and apply the method to estimate brai...
Contribution of Exploratory Methods to the Investigation of Extended Large-Scale Brain Networks in Functional MRI: Methodologies, Results, and Challenges
Functional MRI Methodologies
2009/9/4
A large-scale brain network can be defined as a set of segregated and integrated regions, that is, distant regions that share strong anatomical connections and functional interactions. Data-driven inv...
A case report with changes in BOLD signalling activation areas by improvement of occlusal function in periodontal subjects-the use of analysis by Functional MRI-
initial treatment occlusion fMRI
2009/5/6
We report an interesting case in which improvement of occlusal function in a chronic periodontitis patient was able to be confirmed by the blood oxygenation level-dependent (BOLD) signal on functiona...
