Master’s Program

Behavioral Science

Mental and brain functions can be revealed by analyzing various behaviors in animals, including humans. The Department of Behavioral Science consists of six research groups that investigate psychological functions through multiple approaches in comparative cognitive science, behavioral endocrinology, and behavioral neuroscience (in mice or rats), and the science of mental and developmental disorders (in humans).

Examples of the research themes are behavioral genetics using selective mating; neuroendocrine mechanisms underlying sexual, maternal, and emotional behaviors; neuronal mechanisms underlying learning and memory; psychological and neuronal mechanisms underlying developmental and mental disorders; and clinical practice in higher brain dysfunction.

The Department of Behavioral Science aims to train advanced professionals in behavioral science (science of mind, behavior, and psychological functions) and to train interdisciplinary academic researchers in the fields of comparative psychology, behavioral neuroscience, and mental disorder science.
