Numbers, Information and Complexity is a collection of about 50 articles in honour of Rudolf Ahlswede. His main areas of research are represented in the three sections, `Numbers and Combinations', `Information Theory (Channels and Networks, Combinatorial and Algebraic Coding, Cryptology, with the related fields Data Compression, Entropy Theory, Symbolic Dynamics, Probability and Statistics)', and `Complexity'. Special attention was paid to the interplay between the fields. Surveys on topics of current interest are included as well as new research results. The book features surveys on Combinatorics about topics such as intersection theorems, which are not yet covered in textbooks, several contributions by leading experts in data compression, and relations to Natural Sciences are discussed.

Since its introduction about sixty years ago, stereotactic and functional neurosurgery has evolved into a fascinating and interdisciplinary endeavor that combines modern neurosurgery, neurobiology, and neuroimaging with innovative diagnostic and treatment strategies. In this collection, acknowledged experts from Europe and North and South America present their scientific and clinical experience in stereotactic and functional neurosurgery for movement disorders and brain tumors. The contributions present a wide range from the beginnings of human stereotactic neurosurgery to the most modern molecular and restorative strategies to treat diseases of the human nervous system. They clearly demonstrate that the discipline is still young and dynamic with alternative and sometimes competing strategies whose evaluation is underway. They also document that operative lesioning techniques such as thalamotomies, though still chosen under certain circumstances, have been succeeded by novel neuromodulation techniques such as deep brain stimulation in the great majority of clinical cases.
