Music and control of chaos in the brain

Recent researches revealed that music tends to reduce the degree of chaos in brain waves. For some epilepsy patients music triggers their seizures. Loskutov, Hubler, and others carried out a series of studies concerning control of deterministic chaotic systems. It turned out, that carefully chosen tiny perturbation could stabilize any of unstable periodic orbits making up a strange attractor. Computer experiments have shown a possibility to control a chaotic behavior in neural network by external periodic pulsed force or sinusoidal force. One may propose that the aim of this control is to establish coherent behavior in the brain, because many cognitive functions of the brain are related to a temporal coherence.
