Mass action in brains and computers - a tribute to Walter J. Freeman

摘要

This contribution presents a brief review of experimental and theoretical approaches to brain dynamics, including concepts describing the unity of brain, mind, and body. We dedicate this essay to the memory of Walter J. Freeman, III, with a focus on his pioneering work in the past 60 years establishing the new field of computational neuroscience, including mass action in the nervous system, field theories of cognition and intelligence, and his quest towards inventing novel engineering approaches for brain-machine interfaces.
