Asynchronous and coherent dynamics in balanced excitatory-inhibitory populations

This paper investigates the dynamics of excitatory-inhibitory neural networks, showing how balanced E-I populations can exhibit asynchronous and coherent behaviors, including oscillations and chaos, under different conditions.

Theta-nested gamma oscillations in next generation neural mass models

This paper studies theta-nested gamma oscillations in neural mass models, showing they can emerge from two network configurations with distinct locking behaviors and frequency dynamics.

Coexistence of fast and slow gamma oscillations in one population of inhibitory spiking neurons

This paper shows that a single inhibitory neuron population can generate both slow and fast gamma oscillations through different mechanisms, and demonstrates how external stimuli can switch between these rhythms.
