这本书阐明了随机性和噪音在生物体中的作用。传统上，随机性和噪声被用于理解通信中的信号处理。本书分为两部分，第一部分向读者介绍各种类型和噪声源，以及噪声在非线性动力学中的建设性作用。它还分析了随机性和噪声在各种科学和工程应用中的重要性。接着，第二部分详细讨论了噪声在生物过程中的功能作用，例如，在离子通道、突触水平甚至认知水平上的大脑功能。这些都在不同的章节中描述。寻找各种冥想状态的神经元相关性的一个挑战性问题是理解大脑如何控制各种类型的噪音，从而达到与三昧状态相对应的大脑同步振荡状态。这一点在《噪音、连贯性和冥想》一章中有详细描述。在过去的几十年里，噪音的概念和随机性在生物体中的作用引起了很多争议。这将在另一章中讨论。最后，在生命有机体的背景下，研究了物理学中讨论的随机性的认知和本体性质
Noise and Randomness in Living System
This book illustrates the role of randomness and noise in living organisms. Traditionally, the randomness and noise have been used in understanding signal processing in communications. This book is divided into two sections, the first of which introduces readers to the various types and sources of noise and the constructive role of noise in non-linear dynamics. It also analyses the importance of randomness and noise in a variety of science and engineering applications. In turn, the second section discusses in detail the functional role of noise in biological processes for example, in case of brain function at the level of ion channel, synaptic level and even at cognitive level. These are described in various chapters. One of the challenging issue finding the neuronal correlates of various meditative states is to understand how brain controls various types of noise so as to reach a state of synchronized oscillatory state of the brain corresponding to the state of Samadhi. This is described in details in one chapter called Noise, Coherence and meditation. The concept of noise and the role of randomness in living organism raise lot of controversy for last few decades. This is discussed in a separate chapter. Finally, the epistemic and ontic nature of randomness as discussed in physical science are investigated in the context of living organism
