It took Pavlov until 1883 to complete his dissertation, which he wrote on the functioning of the nerves in the heart (Todes, 2014). Clearly, Pavlov interests were still focused mainly in physiology—not in psychology—at this point in his life. After completing his dissertation, Pavlov decided to travel to Germany where he would work alongside Carl Ludwig on his research on the circulatory system and alongside Rudolf Heidenham on his research on the digestive system (Ivan Petrovich Pavlov, 2015). Gaining this experience, and also learning how to complete several intricate surgical procedures, inspired him to proceed with his main physiological interest—the secretory activity of the digestive system. In 1890, Pavlov was back in St. Petersburg doing his research when he was appointed as the professor of pharmacology at the Military-Medical Academy. Five years later, he was promoted to the professor of physiology (Windholz, 1997). His book Lectures on The Work of the Digestive Glands was published in 1897 and earned him a Nobel Prize in 1904 (Ivan Petrovich Pavlov, 2015; Todes,
