Prasse, B. (author)The field of epidemiology encompasses a broad class of spreading phenomena, ranging from the seasonal influenza and the dissemination of fake news on online social media to the spread of neural activity over a synaptic network. The propagation of viruses, fake news and neural activity relies on the contact between individuals, social media...doctoral thesis 2021

(author), Hillebrand, Arjan (author), Daffertshofer, Andreas (author), Coombes, Stephen (author), Van Mieghem, P.F.A. (author)Large-scale neurophysiological networks are often reconstructed from band-pass filtered time series derived from magnetoencephalography (MEG) data. Common practice is to reconstruct these networks separately for different frequency bands and to treat them independently. Recent evidence suggests that this separation may be inadequate, as there...journal article 2021

Zonneveld, Hazel I. (author), Pruim, R.H.R. (author), Bos, Daniel (author), Vrooman, Henri A. (author), Muetzel, Ryan L. (author), Hofman, Albert (author), Rombouts, Serge ARB (author), van der Lugt, Aad (author), Niessen, W.J. (author)Structural brain markers are studied extensively in the field of neurodegeneration, but are thought to occur rather late in the process. Functional measures such as functional connectivity are gaining interest as potentially more subtle markers of neurodegeneration. However, brain structure and function are also affected by ‘normal’ brain...journal article 2019

Märtens, M. (author)This thesis is a contribution to a deeper understanding of how information propagates and what this process entails. At its very core is the concept of the network: a collection of nodes and links, which describes the structure of the systems under investigation. The network is a mathematical model which allows to focus on a very fundamental...doctoral thesis 2018

Isufi, E. (author), Mahabir, Ashvant S.U. (author), Leus, G.J.T. (author)This letter investigates methods to detect graph topological changes without making any assumption on the nature of the change itself. To accomplish this, we merge recently developed tools in graph signal processing with matched subspace detection theory and propose two blind topology change detectors. The first detector exploits the prior...journal article 2018

(author), White, Tonya (author)Introduction: Typical brain development is characterized by specific patterns of maturation of functional networks. Cortico-cortical connectivity generally increases, whereas subcortico-cortical connections often decrease. Little is known about connectivity changes amongst different subcortical regions in typical development. Methods: This...journal article 2018

Meier, J.M. (author)Over the last two decades the field of network science has been evolving fast. Many useful applications in a wide variety of disciplines have been found. The application of network science to the brain initiated the interdisciplinary field of complex brain networks. On a macroscopic level, brain regions are taken as nodes in a network. The...doctoral thesis 2017

Märtens, M. (author), Meier, J.M. (author), Hillebrand, Arjan (author), Tewarie, Prejaas (author), Van Mieghem, P.F.A. (author)Recent work has revealed frequency-dependent global patterns of information flow by a network analysis of magnetoencephalography data of the human brain. However, it is unknown which properties on a small subgraph-scale of those functional brain networks are dominant at different frequencies bands. Motifs are the building blocks of networks on...journal article 2017

Meier, J. (author), Tewarie, P. (author), Van Mieghem, P. (author)Communication between brain regions is still insufficiently understood. Applying concepts from network science has shown to be successful in gaining insight in the functioning of the brain. Recent work has implicated that especially shortest paths in the structural brain network seem to play a major role in the communication within the brain. So...journal article 2015

Stam, C.J. (author), Tewarie, P. (author), Van Dellen, E. (author), Van Straaten, E.C.W. (author), Hillebrand, A. (author), Van Mieghem, P. (author)In recent years there has been a shift in focus from the study of local, mostly task-related activation to the exploration of the organization and functioning of large-scale structural and functional complex brain networks. Progress in the interdisciplinary field of modern network science has introduced many new concepts, analytical tools and...journal article 2014

Liu, D. (author)The infrastructure networks, including the Internet, telecommunication networks, electrical power grids, transportation networks (road, railway, waterway, and airway networks), gas networks and water networks, are becoming more and more complex. The complex infrastructure networks are crucial to our human society, and it has been a hot research ...doctoral thesis 2013

Stam, C.J. (author), Hillebrand, A. (author), Wang, H. (author), Van Mieghem, P. (author)A network of 32 or 64 connected neural masses, each representing a large population of interacting excitatory and inhibitory neurons and generating an electroencephalography/magnetoencephalography like output signal, was used to demonstrate how an interaction between dynamics and connectivity might explain the emergence of complex network...journal article 2010
