Coherence and chaos walk hand in hand in biological systems. Any living system is a complex entity interacting with the environment in many predictable and some unpredictable ways. Unpredictability stems from the fact that we are not able to understand the workings of the system. Thus, there is a need for mathematical and physical models for many functions of the body. For example, seemingly unrelated and chaotic behavior is considered "normal" in the function of neurons of the brain. Any coherent and correlated discharge of the neurons of the brain is considered unusual indicating need for close monitoring and possible intervention. However, for normal functioning of cardiac muscles, coordinated and systematic discharge of the neurons is necessary. Thus, in different parts of the biological system, different types of activities of the neurons are considered "normal."
