The analysis of two recent models of coupled “next-generation” neural mass models allows us to observe different global mean dynamics of large neural populations. These models describe the mean dynamics of all-to-all coupled networks of quadratic integrate-and-fire spiking neurons. In addition, one of these models considers the influence of the synaptic adaptation mechanism on the macroscopic dynamics. We show how both models are related through a parameter and we study the evolution of the dynamics when switching from one model to the other by varying that parameter. Interestingly, we have detected three main dynamical regimes in the coupled models: Rössler-type (funnel type), bursting-type, and spiking-like (oscillator-type) dynamics. This result opens the question of which regime is the most suitable for realistic simulations of large neural networks and shows the possibility of the emergence of chaotic collective dynamics when synaptic adaptation is very weak. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.4 2024 PHYSICS, MATHEMATICAL 13 / 61 = 0.213 2024 Q1 T1 PHYSICS, FLUIDS & PLASMAS 17 / 41 = 0.415 2024 Q2 T2 0.705 2024 Condensed Matter Physics 2024 Q2 Statistics and Probability 2024 Q2 Statistical and Nonlinear Physics 2024 Q2 4.2 2024 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Jover-Galtier, Jorge A.
