Chaotic heteroclinic networks as models of switching behavior in biological systems
Megan Morrison, Lai-Sang Young
Key features of biological activity can often be captured by transitions between a finite number of semi-stable states that correspond to behaviors or decisions. We present here a…
A data-informed mean-field approach to mapping of cortical parameter landscapes
Zhuo-Cheng Xiao, Kevin K. Lin, Lai-Sang Young
Constraining the many biological parameters that govern cortical dynamics is computationally and conceptually difficult because of the curse of dimensionality. This paper addresses…
Existence of physical measures in some Excitation-Inhibition Networks
Matteo Tanzi, Lai-Sang Young
In this paper we present a rigorous analysis of a class of coupled dynamical systems in which two distinct types of components, one excitatory and the other inhibitory, interact wi…
Simulating brain rhythms using an ODE with stochastically varying coefficients
Benjamin Ambrosio, Lai-Sang Young
The brain produces rhythms in a variety of frequency bands. Some are likely by-products of neuronal processes; others are thought to be top-down. Produced entirely naturally, these…
Nonuniformly hyperbolic systems arising from coupling of chaotic and gradient-like systems
Matteo Tanzi, Lai-Sang Young
We investigate dynamical systems obtained by coupling two maps, one of which is chaotic and is exemplified by an Anosov diffeomorphism, and the other is of gradient type and is exe…
Consequences of delays and imperfect implementation of isolation in epidemic control
Lai-Sang Young, Stefan Ruschel, Serhiy Yanchuk +1
For centuries isolation has been the main control strategy of unforeseen epidemic outbreaks. When implemented in full and without delay, isolation is very effective. However, flawl…
