Noisy network attractor models for transitions between EEG microstates
Jennifer Creaser, Peter Ashwin, Claire Postlethwaite +1
The brain is intrinsically organized into large-scale networks that constantly re-organize on multiple timescales, even when the brain is at rest. The timing of these dynamics is c…
Sequential escapes: onset of slow domino regime via a saddle connection
Peter Ashwin, Jennifer Creaser, Krasimira Tsaneva-Atanasova
We explore sequential escape behaviour of coupled bistable systems under the influence of stochastic perturbations. We consider transient escapes from a marginally stable "quiescen…
Sequential noise-induced escapes for oscillatory network dynamics
Jennifer Creaser, Krasimira Tsaneva-Atanasova, Peter Ashwin
It is well known that the addition of noise in a multistable system can induce random transitions between stable states. The rate of transition can be characterised in terms of the…
