Therefore, we suggest that the microstructural alteration of connectivity-defined subregion projecting from thalamus to temporal cortex could be linked to great memory impairment affecting AD patients.
Alterations of connectivity are central to the systems-level pathophysiology of schizophrenia.
Although our study was limited to a small sample size, our results confirmed that brain functional connectivity in migraine patients showed an alteration of DMN connectivity, suggesting that pain has a widespread impact on brain function, since modify the complex brain networks and beyond pain perception.
Previous RS-fMRI studies investigating brain functional connectivity in patients suffering from different chronic pain conditions have already shown a dramatic alteration of DMN connectivity, suggesting that pain has a widespread impact on overall brain function, modifying brain dynamics beyond pain perception [22, 23].
The distribution pattern of genetic diversity across a species´ range can be influenced by climate change, notably through alteration of geographical connectivity and associated modification of gene flow patterns within and across populations (Huang and Schaal 2012).
Artificial structures do not only modify marine and coastal ecosystems at the sites of their placement, but may also produce larger-scale impacts through their alteration of ecological connectivity - the movement of organisms, materials and energy between habitat units within seascapes.
As expected, a sudden alteration of the connectivity between certain components disrupted task performance generally.
With resting-state fMRI data acquired from chronic heroin users and non-addicted controls, addiction related alteration of functional connectivity of the DMN is demonstrated.
As the anterior cingulate cortex and hippocampus are impaired in drug addiction and meanwhile are parts of the DMN, the present study examined addiction-related alteration of functional connectivity of the DMN.
Therefore, the present study investigated possible addiction related alteration of functional connectivity of the DMN with functional magnetic resonance imaging (fMRI) data acquired during resting state from chronic heroin users and non-addicted controls using ICA.
Compared with healthy controls, T2DM patients showed bidirectional alteration of functional connectivity in several brain regions.
