WebApr 19, 2024 · Alzheimer’s disease has been extensively studied using undirected graphs to represent the correlations of BOLD signals in different anatomical regions through functional magnetic resonance imaging (fMRI). However, there has been relatively little analysis of this kind of data using directed graphs, which potentially offer the potential to capture … WebFeb 13, 2024 · Effect of Slice-Timing on rs-fMRI. The graph theory measures el and eg had the same mean values in the brut and a strategies (Table 1). These results suggested that slice-timing, which is crucial for task-fMRI, may not be mandatory in the rs-fMRI studies at the TR that we used.

WebThe functional knowledge of MDD was mainly obtained from the fMRI and PET studies, which reveal the local differences in blood oxygenation and metabolism of the specific neurotransmitters, respectively. For the structural studies, the T1-based and DTI (diffusion tensor image)-based studies, which defined the abnormalities in cortical thickness ... Webimaging (fMRI) of the brain provides the features for the graph nodes, and brain fiber connectivity is utilized as the structural representation of the graph edges. Self-attention graph pooling (SAGPOOL)-based GNN is then applied to jointly study the function and structure of the brain and identify the biomarkers. The construction of brain network
