For example, in evolution, random errors in the reproduction of the genetic material provides a variation that is fundamental for the selection of adaptive organisms. At the molecular level, thermal fluctuations govern the movements and functions of the macromolecules in the cell. In particular, there is randomness in the structure and function of the neural networks of the brain. More knowledge of the stability requirements of biological processes is needed in order to better understand these problems, which also have important medical applications. Many diseases, for instance certain degenerations of brain cells, are caused by failure of the stabilizing mechanisms in the cell.
Stability is also important, but difficult to achieve, in biotechnological applications.
With the hope of shedding some light on these and related issues, we organized an international workshop on the Role and Control of Random Events in Biological Systems, in Sigtuna, Sweden in September 1995. At this meeting, we focused on neural systems. A number of distinguished scientists with knowledge and insights from different disciplines, such as biology, physics, and computer science, were brought together. We believe this multidisciplinary approach is essential for understanding the phenomenon of life. The result of these efforts is presented in this volume.
