Building predictive models combining structural and functional connectome data via multi-view Graph Neural Networks
Published 2022“…The human brain can be mapped as structural connectivity (SC) data that are the white matter connections measured using Diffusion Tensor Imaging (DTI) and functional connectivity (FC) data which are the corresponding activation regions measured using Functional Magnetic Resonance Imaging (fMRI). The SC and FC data can be processed after neuroimaging to derive connectivity matrices based on predefined regions of interest (ROIs), to obtain nxn matrices for n ROIs. geometric deep learning can be applied on these graph data and these connectivity matrices have been used to give predictions on the age and gender characteristics, which our project replicates. …”

Frequency-Specific Alternations in the Amplitude of Low-Frequency Fluctuations in Chronic Tinnitus
Published 2015-10-01“…Recent resting-state functional magnetic resonance imaging (fMRI) studies suggest that aberrant fluctuations in spontaneous low-frequency oscillations (LFO) of the blood oxygen level-dependent (BOLD) signal may be an important factor in chronic tinnitus; however, the role that frequency-specific components of LFO play in subjective tinnitus remains unclear. …”
