Walter Jackson Freeman III (January 30, 1927 – April 24, 2016), was an American biologist, theoretical neuroscientist[1] and philosopher who conducted research in rabbits' olfactory perception, using EEG.

Based on a theoretical framework of neurodynamics that draws upon insights from chaos theory, he speculated that the currency of brains is primarily meaning, and only secondarily information.

He was also the head of the international advisory council at the Bhaktivedanta Institute for advanced scientific research in consciousness.

Freeman was President of the International Neural Network Society in 1994, and is a Life Fellow of the IEEE.
