Kelso JAS

Glenwood and Martha Creech Chair in Science. Professor of Complex Systems and Brain Sciences Professor of Psychology, Biological Sciences and Biomedical Science. Team Leader of the Human Brain and Behavior Laboratory. Research interests: The problem of coordination in living things; connecting levels of brain and behavior through theory and experiment; principles and mechanisms of coordination dynamics (e.g. in sensorimotor integration, learning, perception, language, and development) using brain imaging (EEG, MEG, fMRI) and behavioral measures. Co-author along with David Engstrøm of The Complementary Nature (MIT Press 2006). Founder and Pioneer of Coordination Dynamics.

Review of TCN

The Complementary Nature ~ A Review by Olaf Sporns “The division of our world (natural and social) into distinct contraries or opposites has become almost universal practice in most fields of human endeavor and inquiry, including science. Undeniably, imposing such divisions on space and time, wave and particle, order and chaos, action and perception, or organism and environment have enabled significant progress in our scientific understanding of these separate domains. However, understanding based on separation or contraries is fundamentally limited, as is powerfully demonstrated by modern physics, biology and neuroscience. Kelso and Engstrøm’s book offers an alternative, synthetic view based on the principle of complementarity, the reconciliation of contraries as jointly necessary and mutually reinforcing aspects of reality. This volume not only presents a comprehensive history of the

“In coordination dynamics, the real-life coordination of neurons in the brain and the real-life coordinated actions of animals are cut, fundamentally, from the same dynamic cloth. Integrity is in turn preserved because it is never threatened. Psychophysical unity is undergirded at all levels by coordination dynamics.” -Maxine Sheets-Johnstone (1930– )
