Warren S. McCulloch was an American neurophysiologist and cybernetician, known for his work on the foundation for certain brain theories and his contribution to the cybernetics movement. Michael Arbib has played a leading role at the interface of neuroscience and computer science ever since his first book, Brains, Machines, and Mathematics. From Neuron to Cognition provides a worthy pedagogical sequel to his widely acclaimed Handbook of Brain Theory and Neural Networks. After thirty years at University of Southern California he is now pursuing interests in ""how the brain got language"" and ""neuroscience for architecture"" in San Diego. The late Seymour A. Papert was a Professor in MIT's AI Lab (1960-1980s) and MIT's Media Lab (1985-2000) and the author of Mindstorms- Children, Computers, and Powerful Ideas.
