Structural connectivity profile supports laterality of the salience network

Human Brain Mapping, 2019
The salience network (SN) is mainly involved in detecting and filtering multimodal salient stimuli, and mediating the switch between the default mode network and central executive network.

Changes in structural and functional connectivity among resting-state networks across the human lifespan

, 2014
At rest, the brain's sensorimotor and higher cognitive systems engage in organized patterns of correlated activity forming resting-state networks. An important empirical question is how functional connectivity and structural connectivity within and ...

Hydrological Connectivity - a study into representative metrics for a humid temperate catchment in northern England. [PDF]

, 2011
Hydrological connectivity has been identified as a concept which can help hydrology move towards a hydrological approach focussing on homogeneity rather than difference.

Convergent reductions in interhemispheric functional, structural and callosal connectivity in Parkinson’s disease

Frontiers in Aging Neuroscience
BackgroundAbnormal interhemispheric functional connectivity is frequently reported in Parkinson’s disease (PD), but its structural basis remains unclear.

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Altered structural brain connectivity in healthy carriers of the autism risk gene, CNTNAP2

, 2011
Recently, carriers of a common variant in the autism risk gene, CNTNAP2, were found to have altered functional brain connectivity using functional MRI. Here, we scanned 328 young adults with high-field (4-Tesla) diffusion imaging, to test the hypothesis ...

Structural plasticity of synaptic connectivity in the adult hippocampal mossy fiber projection [PDF]

, 2013
The brain has the lifelong ability to change itself based on new experiences such as learning and memory. This so called neuronal plasticity is reflected in the brain by structural and functional modifications which underlie our ability to learn ...

Integrating temporal and spatial scales: Human structural network motifs across age and region-of-interest size

Frontiers in Neuroinformatics, 2011
Human brain networks can be characterized at different temporal or spatial scales given by the age of the subject or the spatial resolution of the neuroimaging method. Integration of data across scales can only be successful if the combined networks show

Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.
