Heterogeneous inputs to central pattern generators can shape insect gaits
Zahra Aminzare, Philip Holmes
In our previous work, we studied an interconnected bursting neuron model for insect locomotion, and its corresponding phase oscillator model, which at high speed can generate stabl…
Gait transitions in a phase oscillator model of an insect central pattern generator
Zahra Aminzare, Vaibhav Srivastava, Philip Holmes
Legged locomotion involves various gaits. It has been observed that fast running insects (cockroaches) employ a tripod gait with three legs lifted off the ground simultaneously in…
Explicit moments of decision times for single- and double-threshold drift-diffusion processes
Vaibhav Srivastava, Philip Holmes, Patrick Simen
We derive expressions for the first three moments of the decision time (DT) distribution produced via first threshold crossings by sample paths of a drift-diffusion equation. The "…
A genealogy of convex solids via local and global bifurcations of gradient vector fields
Gábor Domokos, Philip Holmes, Zsolt Lángi
Three-dimensional convex bodies can be classified in terms of the number and stability types of critical points on which they can balance at rest on a horizontal plane. For typical…
Time-varying perturbations can distinguish among integrate-to-threshold models for perceptual decision-making in reaction time tasks
Xiang Zhou, KongFatt Wong-Lin, Philip Holmes
Several integrate-to-threshold models with differing temporal integration mechanisms have been proposed to describe the accumulation of sensory evidence to a prescribed level prior…
Strong NLS Soliton-Defect Interactions
R. H. Goodman, P. J. Holmes, M. I. Weinstein
We consider the interaction of a nonlinear Schrodinger soliton with a localized (point) defect in the medium through which it travels. Using numerical simulations, we find paramete…
