Dear all

This is a kind reminder of the new "SPIN" seminar on Neuroscience for this January 30th 2026:

*Date: Friday January 30th 2026

*Place: Seminario del Centro de Instrumentación Científica de la UGR

*Time: 11:00

Title: Dynamics in mean-field neural models: applications

Abstract:

In this talk we study the dynamics of two recently introduced mean-field models representing the behavior of heterogeneous all-to-all coupled quadratic integrate-and-fire neural networks. Firstly we study the phenomena that when there are synaptic dynamics in the model, which allows a delay in synaptic transmission, it seems to reduce the emergence of chaotic dynamics by increasing the synaptic time constant and maintains a phase-locked state in the form of bursting dynamics in the mean-field model. We examine in depth the different dynamical behaviors that can be found in both mean-field models (spiking, bursting, and Rossler-like chaotic behaviors) and study in detail the bifurcations underlying their appearance and disappearance. Moreover, we relate the disappearance of various behaviors with the recently introduced geometric bifurcations. And secondly, we focus on the use of mean-field models in a theoretical study of tonic-clonic epileptic seizures. These are a particularly important class of epilepsy and have previously been theorised to arise in systems with an instability from one temporal rhythm to another via a quasi-periodic transition. We show that a recently introduced class of next generation neural field models has a sufficiently rich bifurcation structure to support such behaviour.
