Coherent dynamics in soft-threshold integrate-and-fire networks
Lauren Forbes, Jared Grossman, Montie Avery +2
We study bifurcations in networks of integrate-and-fire neurons with stochastic spike emission, focusing on the effects of the spatial and temporal structure of the synaptic intera…
Empirical scaling laws in balanced networks with conductance-based synapses
Vicky Zhu, Gabriel Ocker, Robert Rosenbaum
Strongly coupled, recurrent, balanced network models have been successful in describing and predicting many phenomena observed in cortical neural recordings. However, most balanced…
The Impact of Structural Changes on Learning Capacity in the Fly Olfactory Neural Circuit
Katherine Xie, Gabriel Koch Ocker
The Drosophila mushroom body (MB) is known to be involved in olfactory learning and memory; the synaptic plasticity of the Kenyon cell (KC) to mushroom body output neuron (MBON) sy…
Field-theoretic approach to compartmental neuronal networks: impact of dendritic calcium spike-dependent bursting
Audrey O'Brien Teasley, Gabriel Koch Ocker
Neurons are spatially extended cells; different parts of a neuron have specific voltage dynamics. Important types of neurons even generate different spikes in different parts of th…
Diverse mean-field dynamics of clustered, inhibition-stabilized Hawkes networks via combinatorial threshold-linear networks
Caitlin Lienkaemper, Gabriel Koch Ocker
Networks of interconnected neurons display diverse patterns of collective activity. Relating this collective activity to the network's connectivity structure is a key goal of compu…
Metastability in networks of nonlinear stochastic integrate-and-fire neurons
Siddharth Paliwal, Gabriel Koch Ocker, Braden A. W. Brinkman
Neurons in the brain continuously process the barrage of sensory inputs they receive from the environment. A wide array of experimental work has shown that the collective activity…
