Muhua Zheng – Geometric renormalization unravels self-similarity of the multiscale human connectome (spotlight talk)

by Muhua Zheng (University of Barcelona). Structural connectivity in the brain is typically studied by reducing its observation to a single spatial resolution. However, the brain possesses a rich architecture organized over multiple scales linked to one another. We explored the multiscale organization of human connectomes using datasets of healthy subjects reconstructed at five different … Continue reading Muhua Zheng – Geometric renormalization unravels self-similarity of the multiscale human connectome (spotlight talk)

Benedetta Mariani – Brain criticality beyond resting state neuronal avalanches (spotlight talk)

by Benedetta Mariani (University of Padova, Padova Neuroscience Center). The critical brain hypothesis has been extensively studied since the first experimental signature [1], because criticality optimizes important quantities for information processing. However, the hypothesis remains debated. On the one hand, the actual foundations of the hypothesis – the self-organization process and how it manifests during … Continue reading Benedetta Mariani – Brain criticality beyond resting state neuronal avalanches (spotlight talk)

Joel Hochstetter – Avalanches and the edge-of-chaos in neuromorphic nanowire networks (spotlight talk)

by Joel Hochstetter (University of Sidney). The brain's efficient information processing ability has inspired the development of neuromorphic systems constructed from nanoscale material structures exhibiting ``brain-like'' responses to electrical stimulation. Here we report on one such system, neuromorphic nanowire networks. Bio-inspired self-assembly of these nanowire networks confers a complex neural network-like structure, while nanowire-nanowire junctions … Continue reading Joel Hochstetter – Avalanches and the edge-of-chaos in neuromorphic nanowire networks (spotlight talk)

Daniel Korchinski – Criticality without time-scale separation between avalanche initiation and spreading (spotlight talk)

by Daniel Korchinski (Complexity Science Group, University of Calgary, Stewart Blusson Quantum Matter Institute, University of British Columbia). Spreading processes on networks are ubiquitous in both human-made and natural systems. Understanding their behavior is of broad interest; from the control of epidemics to understanding brain dynamics. While in some cases there exists a clear separation … Continue reading Daniel Korchinski – Criticality without time-scale separation between avalanche initiation and spreading (spotlight talk)

Kanika Bansal – Cognitive connotations of neural avalanches in human brain dynamics (spotlight talk)

by Kanika Bansal (CCDC US Army Research Laboratory & Columbia University, New York, NY, USA). Analyses of neural avalanches, in combination with other methods rooted in complex systems theory, provide support for the brain criticality hypothesis, however, it is still unclear how the criticality framework would account for the omnipresent cognitive variability, across individuals and … Continue reading Kanika Bansal – Cognitive connotations of neural avalanches in human brain dynamics (spotlight talk)
