Analytical Characterization of Epileptic Dynamics in a Bistable System

no code implementations4 Apr 2024 Yuzhen Qin, Ahmed El-Gazzar, Danielle S. Bassett, Fabio Pasqualetti, Marcel van Gerven

In this paper, we employ a bistable model, where a stable equilibrium and a stable limit cycle coexist, to describe epileptic dynamics.
