Definition
Dynamical systems describe orbits or trajectories as they evolve in time-space. The brain is a dynamical system whose macroscopic behavior may be couched in terms of normal (e.g., waking, attentive, etc.) or abnormal (e.g., coma, seizure or post-seizure, etc.) states. Brain stability may be defined as the proneness of a trajectory or orbit to remain in its “neighborhood” in the presence of perturbations. The terms bistability and multistability denote the coexistence of more than one simultaneously “stable” states in a system.
Epilepsy is a disorder characterized by the aperiodic emergence of unprovoked seizures that in 20–40 % of sufferers are uncontrollable by medications. Behaviorally, seizures are characterized by one or more of involuntary movements, sensations, perceptions, and loss of awareness or of consciousness. Electrically, seizures manifest as aberrant increases in power of neuronal...
