Evidence for quasicritical brain dynamics
Leandro Fosque, Rashid V. Williams-Garcia, John M. Beggs +1
Much evidence seems to suggest cortex operates near a critical point, yet a single set of exponents defining its universality class has not been found. In fact, when critical expon…
Unveiling causal activity of complex networks
Rashid V. Williams-Garcia, John M. Beggs, Gerardo Ortiz
We introduce a novel tool for analyzing complex network dynamics, allowing for cascades of causally-related events, which we call causal webs (c-webs), to be separated from other n…
Quasi-Critical Brain Dynamics on a Non-Equilibrium Widom Line
Rashid V. Williams-Garcia, Mark Moore, John M. Beggs +1
Is the brain really operating at a critical point? We study the non-equilibrium properties of a neural network which models the dynamics of the neocortex and argue for optimal quas…
Multivariate information measures: an experimentalist's perspective
Nicholas Timme, Wesley Alford, Benjamin Flecker +1
Information theory is widely accepted as a powerful tool for analyzing complex systems and it has been applied in many disciplines. Recently, some central components of information…
A general approach for analyzing baseline power spectral densities: Zwanzig-Mori projection operators and the generalized Langevin equation
David Hsu, Murielle Hsu, John M. Beggs
There continues to be widespread interest in 1/f^(alpha) behavior in baseline power spectral densities (PSD's) but its origins remain controversial. Zwanzig-Mori projection operato…
A simple spontaneously active Hebbian learning model: homeostasis of activity and connectivity, and consequences for learning and epileptogenesis
David Hsu, Aonan Tang, Murielle Hsu +1
A spontaneously active neural system that is capable of continual learning should also be capable of homeostasis of both firing rate and connectivity. Experimental evidence suggest…
