WebJul 1, 2024 · The small-worldness of the brain network emerged as a moderator of the association between intellectual engagement and cognition. Exclusively among elderly people with lower small-worldness, greater intellectual engagement, including the frequency and participation hours of activities, was associated with greater global cognitive … WebJun 1, 2024 · Small-world human brain networks of healthy adults, including the structural covariance network (top), the white matter structural network (middle) and the functional …
WebThe statistics based on brain networks were calculated the differences between the patients and the healthy. Several topological properties were computed, such as the small-worldness, nodal clustering coefficient, characteristic path length, and degree centrality. WebSmall-world neural networks in the brain. Both anatomical connections in the brain and the synchronization networks of cortical neurons exhibit small-world topology. Structural …
WebOct 10, 2024 · It is important to bear in mind that applications of small-worldness and other graph-theoretical measures to brain networks are inherently limited by the noisiness of imaging modalities, such as ... WebThis study aimed to investigate the topological characteristics of the resting-state functional network and the underlying pathological mechanism in nondialysis patients with stage 5 chronic kidney disease (CKD5 ND).
