Hisao Nishijo received the National License in Medicine from the Ministry of Public Welfare of Japan, in 1982, and obtained his M.D. degree from the Toyama Medical and Pharmaceutical University, in 1986, under the supervision of Professor Taketoshi Ono. Then, Dr. Nishijo served as an Assistant Professor in 1986 and was promoted to be an Associate Professor in 1993 at the Department of Physiology, School of Medicine, Toyama Medical and Pharmaceutical University. During this period, he had the opportunity to work with Dr. Ralph Norgren as a Visiting Assistant Professor at the Pennsylvania State University, from 1987 to 1989. Since 1998, Dr. Hisao Nishijo has been working as a Professor at and the Chairman of the Department of System Emotional Science (Department of Physiology), Faculty of Medicine and Pharmaceutical Sciences (Medicine), at the University of Toyama, Japan. For more than twenty years, Dr. Nishijo has been engaged in studying the neuronal involvement in the emotional and motivated behavior in mice, rats, monkeys, and humans, showing that the amygdala is involved in the recognition and evaluation of the biological significance of a stimulus and the pulvinar, in the recognition of a face-like pattern, and that the nucleus accumbens (NAc) shell is deeply involved in the sexual behavior and that changes in NAc shell neuronal activity are related to the performance of the sexual behavior, encoding cues or contexts related to the sexual behavior, reward-related processing, and the inhibition of the sexual behavior after ejaculation. He is also analyzing monkey's hippocampal neurons during the virtual navigation.
