For more than one century, brain processing was mainly thought in a localizationist framework, which given function underpinned by discrete, isolated cortical area, and with similar cerebral organization across individuals. However, advances mapping techniques humans have provided new insights into the organizational principles of anatomo-functional architecture. Here, we review recent findings gained from neuroimaging, electrophysiological, as well lesion studies. Based on these data connectome, challenge traditional, outdated view propose an alternative meta-networking theory. This model holds that complex cognitions behaviors arise spatiotemporal integration distributed but relatively specialized networks underlying conation cognition (e.g., language, spatial cognition). Dynamic interactions between such circuits result perpetual succession equilibrium states, opening door to considerable interindividual behavioral variability neuroplastic phenomena. Indeed, underlies uniquely human propensity learn abilities, also explains how postlesional reshaping can lead some degrees functional compensation brain-damaged patients. We discuss major implications this approach fundamental neurosciences for clinical developments, especially neurology, psychiatry, neurorehabilitation, restorative neurosurgery.

The brain recruits neuronal populations in a temporally coordinated manner task and at rest. However, the extent to which large-scale networks exhibit their own organized temporal dynamics is unclear. We use an approach designed find repeating network patterns whole-brain resting fMRI data, where are defined as graphs of interacting areas. that transitions between nonrandom, with certain more likely occur after others. Further, this nonrandom sequencing itself hierarchically organized, revealing two distinct sets networks, or metastates, has tendency cycle within. One metastate associated sensory motor regions, other involves areas related higher order cognition. Moreover, we proportion time subject spends each consistent subject-specific measure, heritable, shows significant relationship cognitive traits.

The brain is a complex, multiscale dynamical system composed of many interacting regions. Knowledge the spatiotemporal organization these interactions critical for establishing solid understanding brain's functional architecture and relationship between neural dynamics cognition in health disease. possibility studying through careful analysis neuroimaging data has catalyzed substantial interest methods that estimate time-resolved fluctuations connectivity (often referred to as "dynamic" or time-varying connectivity; TVFC). At same time, debates have emerged regarding application TVFC analyses resting fMRI data, about statistical validity, physiological origins, cognitive behavioral relevance TVFC. These other unresolved issues complicate interpretation findings limit insights can be gained from this promising new research area. This article brings together scientists with variety perspectives on review current literature light issues. We introduce core concepts, define key terms, summarize controversies open questions, present forward-looking perspective how rigorously productively applied investigate wide range questions systems neuroscience.

The organization of the brain network enables its function. Evaluation this has revealed that large-scale networks consist multiple segregated subnetworks interacting areas. Descriptions resting-state architecture have provided clues for understanding functional significance these subnetworks, many which correspond to distinct systems. present report synthesizes accumulating evidence reveal how maintaining systems renders human functionally specialized, adaptable task demands, and largely resilient following focal damage. organizational properties support system segregation are harmonious with promote integration across network, but confer unique important features central function behavior.

Abstract The brain is constituted of multiple networks functionally correlated areas, out which the default-mode network (DMN) largest. Most existing research into DMN has taken a corticocentric approach. Despite its resemblance with unitary model limbic system, contribution subcortical structures to may be underappreciated. Here, we propose more comprehensive neuroanatomical including such as basal forebrain, cholinergic nuclei, anterior and mediodorsal thalamic nuclei. Additionally, tractography diffusion-weighted imaging was employed explore structural connectivity, revealed that thalamus forebrain are central importance for functioning DMN. these neurochemically diverse nuclei reconciles previous neuroimaging neuropathological findings in diseased brains offers potential identifying conserved homologue other mammalian species.
