-------------------------------------------
The focus of this book is on a currently emerging body of research ---computational architectures integrating neural and symbolic processes.  There has been a great deal of work in integrating neural andsymbolic processes, both from a cognitive and/or applicational viewpoint,The editors of this book intend to address the underlying architectural aspects of this integration. In order to provide a basis for a deeper understanding of existing divergent approaches and provide insight for further developments in this field, the book presents (1) an examination of specific architectures (grouped together according to their approaches), theirstrengths and weaknesses, why they work, and what they predict, and (2) a critique/comparison of these approaches.

The book will be of use toresearchers, graduate students, and interested laymen, in areas such as cognitive science, artificial intelligence, computer science, cognitivepsychology, and neurocomputing, in keeping up to date with the newest researchtrends. It can also serve as a comprehensive, in-depth introduction to thisnew emerging field. A unique feature of the book is a comprehensive bibliography at the end of the book.
