Social Discounting Enables Fast and Reliable Collective Escape
Zachary P Kilpatrick
Solitary animals face a tradeoff when detecting threats: faster detection means accepting more false alarms. We show that groups can manage this tradeoff better by treating an undi…
Resource depletion accelerates rate learning but not composition learning in patch foraging
Zachary P. Kilpatrick, Ahmed El Hady
Foraging is a universal animal behavior that has increasingly attracted the interest of both experimentalists and theorists. Most prior models assume an animal knows the distributi…
Astrocytic resource diffusion stabilizes persistent activity in neural fields
Noah Palmer, Heather L. Cihak, Daniele Avitabile +1
Persistent neural activity underlying working memory requires sustained synaptic transmission, yet the metabolic and neurotransmitter support provided by astrocyte networks is larg…
Modularity, asymmetry, and polarization shape consensus speed in the voter model
Madi Yerlanov, Zachary Kilpatrick, Nancy Rodriguez
In populations with community structure, the formation of consensus requires both alignment within and diffusion of beliefs across groups, processes that evolve on distinct time sc…
Stroboscopic motion reversals in delay-coupled neural fields
Noah Parks, Zachary P Kilpatrick
Visual illusions provide a window into the mechanisms underlying visual processing, and dynamical neural circuit models offer a natural framework for proposing and testing theories…
Radial Basis Function Techniques for Neural Field Models on Surfaces
Sage B Shaw, Zachary P Kilpatrick, Daniele Avitabile
We present a numerical framework for solving neural field equations on surfaces using Radial Basis Function (RBF) interpolation and quadrature. Neural field models describe the evo…
