On this encore edition of StudioTulsa, we visit with John M. Henshaw, the Harry H. Rogers Professor of Mechanical Engineering and chair of the Department of Engineering here at the University of Tulsa. Professor Henshaw's new book is "A Tour of the Senses: How Your Brain Interprets the World." This book offers an engaging and accessible consideration of the five senses --- taste, smell, touch, sight, and hearing --- and, moreover, of how these senses influence and affect one another. Much attention is also paid to the complexities and mysteries surrounding how our brains actually interpret sensory data, and to the long-running history of the study of sensory perception (which goes back to Aristotle). As Professor Henshaw explains, the various ways by which modern science and technology have advanced our understanding of sensory intake have led him to believe that we possess, in fact, four additional senses: pain, temperature, balance, and body awareness.
