In 1967, together with L.M. Ricciardi, he proposed a quantum theory of the brain which posits a spatially distributed charge formation exhibiting spontaneous breakdowns at micro levels as the basis for processing at macro levels. In this model, the information resides in the virtual field associated
265:
with the dynamics of the cellular matter. This model was subsequently expanded by Stuart, Takahashi and
Umezawa with their proposal of the development of long range correlations among neurons due to the interaction of two quantum fields. The approach was built upon by many others, including

Umezawa is recognized as one of the eminent quantum field theorists of his generation. He applied his results in quantum field theory also to
242:, Canada, in 1975 when he took the Killam Memorial Chair as Professor of Physics, a position which he held until his retirement in 1992.
