The analyses had been done at the local (hubs and activated links and areas), meso (clustering, assortativity, and rich-club), and global (small-world, small-worldness, and efficiency) topological scales. The results showed that the trends of changes in the topological architecture of the ...
The complex spatio-temporal patterns of activity exhibited by the brain derive from the interplay between the neural dynamics of cortical areas and their connectivity. From a modeling standpoint, one of the most challenging problems is the inference of network parameters in a brain model to reproduce...
Thus, most large areas can be divided into a mosaic of component regions, separate parts that differ from their neighbors in some ways. Each of these regions may be distinct, sharing no characteristics with any of the others, or some may be similar in all (or the majority of) respects ...
However, the extent and location of changes in brain areas caused by exposure to monochromatic light remain largely unknown. This pilot study (N = 7) using resting-state functional magnetic resonance shows light-dependent functional connectivity patterns on brain networks. We demonstrated that 1...
The target areas described in the NIBS studies were cortical regions in the brain that are specified by their respective Brodmann areas68 while we identified node-level differences in areas of the Schaefer 200 atlas. We used the MRIcron tool101 to map each of the Brodmann areas to Schaefer ...
(Fig.2B). We observed that the inter-individual variability in functional network topography was highest in the association cortex, including the prefrontal and temporo-parietal areas, and lowest in the primary sensorimotor cortex. Finally, we ordered the median value of the inter-individual ...
Diagram showing the eyes and visual projection systemAnatomical basis for vision The anatomical structures involved in vision include the eyes, optic nerves and tracts, optic thalamus, primary visual cortex, and higher visual areas of the brain. The eyes are motor organs as well as sensory; that...
The extent of resection of glioma is one of the most important predictors of the survival duration of patients after surgery. The presence of eloquent areas within or near a tumor often limits resection, as resection of these areas would result in functional loss and reduced quality of life. ...
Spontaneous fluctuations in functional magnetic resonance imaging (fMRI) signals correlate across distant brain areas, shaping functionally relevant intrinsic networks. However, the generative mechanism of fMRI signal correlations, and in particular the
spatially segregated cortical columns is a ubiquitous feature of sensory cortices across various species, including tonotopic maps in the auditory cortex, taste maps in the gustatory cortex, somatotopic maps in somatosensory areas, and dominance and orientation maps in the visual cortex2,74,75,76,77...
