Efficient Network Reconstruction from Dynamical Cascades Identifies Small-World Topology of Neuronal Avalanches
Cascading activity is commonly found in complex systems with directed interactions such as metabolic networks, neuronal networks, or disease spreading in social networks. Substantial insight into a system's organization can be obtained by reconstructing the underlying functional network architecture from the observed activity cascades. Here we focus on Bayesian approaches and reduce their compu...
متن کاملDisrupted small-world brain network topology in pure conduct disorder
OBJECTIVES Conduct disorder (CD) is characterized by the violation of the rights of others or basic social rules and a repetitive, persistent pattern of antisocial and aggressive behaviors. A large number of functional and structural neuroimaging studies have identified widely abnormalities in specific brain regions in CD, but the alterations in the topological organization of functional networ...
متن کاملNetwork-Structured Particle Swarm Optimizer with Small-World Topology
This study proposes Network-Structured Particle Swarm Optimizer (NS-PSO) with Small-World topology. All particles are connected to adjacent particles depending on the small-world network. The directly connected particles share their own best position. Each particle is updated depending on the neighborhood distance on the network between it and a winner, whose function value is best among all pa...
متن کاملHomeostatic presynaptic suppression of neuronal network bursts.
Spontaneous synchronized bursts of activity play an essential role in the maturation and plasticity of neuronal networks. To investigate the cellular properties that enable spontaneous network activity, we used dissociated cultures of hippocampal neurons that express prolonged network activity bursts. Acute exposure to a low concentration of N-methyl-d-aspartate (NMDA) caused an increase in spo...
متن کاملExtraction of Network Topology From Multi-Electrode Recordings: Is there a Small-World Effect?
The simultaneous recording of the activity of many neurons poses challenges for multivariate data analysis. Here, we propose a general scheme of reconstruction of the functional network from spike train recordings. Effective, causal interactions are estimated by fitting generalized linear models on the neural responses, incorporating effects of the neurons' self-history, of input from other neu...
