Age-Related Changes in Task Related Functional Network Connectivity
Aging has a multi-faceted impact on brain structure, brain function and cognitive task performance, but the interaction of these different age-related changes is largely unexplored. We hypothesize that age-related structural changes alter the functional connectivity within the brain, resulting in altered task performance during cognitive challenges. In this neuroimaging study, we used independe...
متن کاملAge-related increases in long-range connectivity in fetal functional neural connectivity networks in utero
Formation of operational neural networks is one of the most significant accomplishments of human fetal brain growth. Recent advances in functional magnetic resonance imaging (fMRI) have made it possible to obtain information about brain function during fetal development. Specifically, resting-state fMRI and novel signal covariation approaches have opened up a new avenue for non-invasive assessm...
متن کاملAge-Related Changes in Frontal Network Structural and Functional Connectivity in Relation to Bimanual Movement Control.
UNLABELLED Changes in both brain structure and neurophysiological function regulating homotopic as well as heterotopic interhemispheric interactions (IHIs) are assumed to be responsible for the bimanual performance deficits in older adults. However, how the structural and functional networks regulating bimanual performance decline in older adults, as well as the interplay between brain structur...
متن کاملAge-Related Reorganizational Changes in Modularity and Functional Connectivity of Human Brain Networks
The human brain undergoes both morphological and functional modifications across the human lifespan. It is important to understand the aspects of brain reorganization that are critical in normal aging. To address this question, one approach is to investigate age-related topological changes of the brain. In this study, we developed a brain network model using graph theory methods applied to the ...
متن کاملAge-related changes in retinal functional topography.
PURPOSE To perform a detailed topographical analysis of functional age-related changes over the retina. METHODS Fifty-nine normal phakic subjects aged 10 to 69 years were divided into six groups, according to decade of age. mfERG traces were recorded from the central 60 degrees of the retina, with a resolution of 61 and 103 scaled hexagons. Group medians of peak amplitude and latency of the f...
