Jacob Steiner

Jacob Steiner (Steiner Erik, Budapest) is a professor at Hebrew University of Jerusalem, and a researcher of the physiology of the senses.

He received his Ph.D. from University of Basel in 1964.

He became a lecturer in 1965, a senior lecturer in 1974, an associate professor in 1979 and became emeritus in 1996.

He was a visiting Associate Professor to the University of Pennsylvania. He was a visiting Professor to Brown University. He was a visiting Scholar at Monell Chemical Senses Center, in Philadelphia.

He did research on the physiology of the senses of taste and smell in man and in animals and their clinical trial. On the behavioral, electrophysiological and autonomous reactions to chemical stimuli. And on the developmental aspects of oral functions.

"Steiner’s research, which involved infants only a few hours old, clearly shows that humans are born with the capacity to distinguish between various tastes. Jacob E. Steiner, a taste researcher at Hebrew University in Jerusalem, almost all babies, when tasting sweet stimuli, show a ’’marked relaxation of the face, resembling an expression of ’satisfaction.’ ’’ This expression is often followed by a slight smile and even ’’eager licking of the upper lip.’’ When the babies were fed a bitter solution, on the other hand, their facial expressions turned to ’’dislike and disgust or rejection.’’" New York Times April 16.1989. Can Society Tell You What Tastes Good?

"The meticulous observation, semiquantitative analysis and evaluation of behavioral reactions is proposed as one of the most relevant and valid avenues of investigation on the workup of chemosensory stimuli by the living organism. Behavioral manifestations, are probably even in a much easier way "readable" indicators of pleasure and displeasure than any other event-related bodily manifestation. In fact, the phenomenon of bacterial chemotaxis (as usually divided in positive- respectivel y negative chemotaxis) belong to the same category or kind of innate, probably even inherited reflectory mechanisms expressing " acceptance" - 'indifference' and 'aversion' of the organism."
