Simulated nonlinear oscillations arising from 3 Hz modal instability in a corticothalamic neural field model.
(A) Stochastic activity either side of the seizure can be seen, reflecting the response properties of the stable steady state mode. The large amplitude oscillations arise from a transient change in a corticothalamic state parameter from t = 5 s to t = 20 s. (B) Shows more detail of the aperiodic oscillations.
