N-Body Oscillator Interactions of Higher-Order Coupling Functions

no code implementations14 Aug 2023 Youngmin Park, Dan Wilson

Second, we use $N=3$ realistic conductance-based thalamic neuron models and show that our method correctly predicts a loss in stability of a splay state for non-weak synaptic coupling.

Models of Vimentin Organization Under Actin-Driven Transport

1 code implementation6 Sep 2022 Youngmin Park, Cécile Leduc, Sandrine Etienne-Manneville, Stéphanie Portet

This modeling approach allows us to conclude that our experimental data are best explained by a spatially dependent trapping of intermediate filaments or a spatially dependent speed of actin-dependent transport.

Coarse-grained Stochastic Model of Myosin-Driven Vesicles into Dendritic Spines

1 code implementation15 Jul 2021 Youngmin Park, Prashant Singh, Thomas G. Fai

We consider the stochastic analog of the vesicle transport model in [Park and Fai, The Dynamics of Vesicles Driven Into Closed Constrictions by Molecular Motors.

High-Order Accuracy Computation of Coupling Functions for Strongly Coupled Oscillators

1 code implementation2 Oct 2020 Youngmin Park, Dan Wilson

First, we use diffusively coupled complex Ginzburg-Landau (CGL) model and demonstrate that our theory accurately predicts bifurcations far beyond the range of existing coupling theory.

Dynamics of Vesicles Driven Into Closed Constrictions by Molecular Motors

1 code implementation10 Apr 2020 Youngmin Park, Thomas G. Fai

The model's key parameters are the ratio of motors that prefer to push toward the head of the dendritic spine to the ratio of motors that prefer to push in the opposite direction.

Scalar Reduction of a Neural Field Model with Spike Frequency Adaptation

1 code implementation18 Jan 2018 Youngmin Park, G. Bard Ermentrout

We also show existence and stability of constant velocity solutions on both domains using Evans functions.

The Utility of Phase Models in Studying Neural Synchronization

1 code implementation18 Jul 2017 Youngmin Park, Stewart Heitmann, G. Bard Ermentrout

The phase response curves and the form of coupling between reciprocally coupled oscillators defines the phase interaction function, which in turn predicts the synchronization outcome (in-phase versus anti-phase) and the rate of convergence.

Weakly Coupled Oscillators in a Slowly Varying World

1 code implementation8 Mar 2016 Youngmin Park, Bard Ermentrout

We extend the theory of weakly coupled oscillators to incorporate slowly varying inputs and parameters.
