and to make possible the results of tomorrow and the next 10 years.

Third, the symposium was an event for the public: a chance for interested people in all fields to learn about the latest work and to share for a day or two in the heady sensation of surveying a scientific frontier together with some of the leading workers who are currently exploring it. The American public has been and continues to be the principal sponsor of scientific research; and in the study of the human brain, in particular, a great share of the field's excitement, as well as a clear presentation of its principles and methods, is owed to the public. This book aims to present both, with a minimum of jargon and with the optimum of interest and accessibility. Not only as sponsors of research, but as living, thinking exemplars of the infinitely varied creativity of the human brain, we are all entitled to share in the promise of neuroscience.

Chapter 1 is based on presentations by Maxwell Cowan, Enoch Gordis, and Dominick Purpura.
