Fiber tractography uses diffusion MRI to estimate the trajectory and cortical projection zones of white matter fascicles in the living human brain. There are many different tractography algorithms and each requires the ...

En este trabajo proponemos que tras la caída de la hipótesis de cascada amiloide en al enfermedad del Alzheimer (EA), la conectividad cerebral distribuida (que va más allá de regiones clásicamente asociadas a AD, como el ...

Mapping structural brain connectomes for living human brains typically requires expert analysis and rule-based models on diffusion-weighted magnetic resonance imaging. A data-driven approach, however, could overcome ...

In complex systems such as the brain, interactions among their constituents units have been demonstrated to occur in groups of units and not limited only to pairwise interactions, like for example, neural coupling among ...

The relation between large-scale brain structure and function is an outstanding open problem in neuroscience. We approach this problem by studying the dynamical regime under which realistic spatiotemporal patterns of brain ...

Evidence of critical dynamics has been found recently in both experiments and models of large-scale brain dynamics. The understanding of the nature and features of such a critical regime is hampered by the relatively small ...

La cognición humana depende en las fluctuaciones de la actividad cortical para realizar tareas o entrar en la percepción consciente. Las fluctuaciones también ocurren espontáneamente, lo que está influido por condicionantes ...
