What is the place of Psychophysiology in the Interdisciplinary Sciences? Welcoming address of the Vice-President (Academic Affairs) at the Opening Ceremonies of the 12th World Congress of Psychophysiology, I.O.P. 2004.

What is Psychophysiology, what is physiology? Are they bridges between physics, physiology and psychophysiology? Do we again need a common language in the 21st century? ‘‘Psychophysiology’’, as an integration of physiology and neuroscience, provides the only in vivo theoretical framework with a panoply of electrophysiological and neuroimaging techniques for the establishment of methodologically essential and crucial links for the investigation, understanding and mapping of brain functions pertaining to basic cognitive, emotional and motivational processes as well as to normal and pathological conditions (Mangina, 2003). Further, according to President C.A. Mangina, psychophysiologists are scientists integrating scopes of several disciplines. From the days of Helmholtz, the evolution of ‘‘Brain Dynamics and Memory ’’ was realized by neurologists, psychiatrists, psychologists, neurosurgeons, neurophysiologists, and biophysicists, who also contributed to the integration of all these disciplines, namely to ‘‘psychophysiology’’. Can the four ‘‘P’’s–Physics, Physiology, Psychology and Physiology –provide a common language or common links? I favor the following view: a union between biophysics, (which combines realms of physics, physiology and molecular biology) and psychology is indispensable. Both disciplines are inseparable. In the 19th century, Hermann von Helmholtz being an experimental biophysicist, unified the four P’s at the beginning without gloriously emphasizing this. He did not only launch predictions but also provided a
