Andrew's book introduces the reader to numerous very interesting problems associated with the development of large computers and methods for solving various problems on them, as well as a wide range of questions that arise when studying the living brain. The issues the book focuses on are not new. They are widely discussed in substantial monographs, journal articles, non-fiction books and newspaper notes. Nevertheless, the reader will find a lot of new things in the book, and those who know the factual material well will be interested in deep comparisons and far-reaching analogies of the living brain and the computer.
