E-Book Overview
The two-volume set LNCS 2686 and LNCS 2687 constitute the refereed proceedings of the 7th International Work-Conference on Artificial and Natural Neural Networks, IWANN 2003, held in Ma?, Menorca, Spain in June 2003.
The 197 revised papers presented were carefully reviewed and selected for inclusion in the book and address the following topics: mathematical and computational methods in neural modelling, neurophysiological data analysis and modelling, structural and functional models of neurons, learning and other plasticity phenomena, complex systems dynamics, cognitive processes and artificial intelligence, methodologies for net design, bio-inspired systems and engineering, and applications in a broad variety of fields.

Our dream has been, and still is: (1) find ways to understand the physiological, symbolic and cognitive nature of the nervous system (NS) with the help of computational and engineering tools; and (2) find rich and insightful sources of inspiration in biology, to develop new materials, mechanisms and problemsolving methods (PSM) of value in engineering and computation. As all of us know well, this dream started with the Ancient Greeks, reappeared in the foundational stage of neurocybernetics and bionics, and is now broadly accepted in the scientific community under different labels such as computational neuroscience (CN) and artificial neural nets (ANN), or genetic algorithms and
