University of Tsukuba


The University of Tsukuba is located in the suburbs of Tokyo and is at the heart of Tsukuba Science City —Japan’s largest “science city,” which has 29 national research institutes and about 150 private research organizations. The University operates on the principle that it is open to all.

The University of Tsukuba aims to cross the borders that separate a variety of organizations, such as those between nations, research institutions, and fields of study. The University’s network is expanding globally. In particular, the University has entered into ten campus-in-campus arrangements with universities in eight countries and regions, thereby promoting close cooperative relationships between education and research. At present, the University hosts approximately 2,200 study abroad students from more than 110 countries and regions.

Collaboration is essential in order to achieve high-quality outcomes with limited resources. As an example, the University is actively engaged in an exchange of talent and joint research that goes beyond the conventional university framework at nationwide joint-use institutes that encompass the four fields of computational science, marine science, plant science, and plasma research.

The Research and Development Centers are the part of the University’s quest to pursue research and innovation that result in benefits for society. Externally funded, twelve centers are newly established as industry-university-government partnerships for joint research in areas of high demand from the community.

The University is also proactively engaging in the support of venture corporations. Thus far, a total of 160 companies have originated from the University of Tsukuba, including Cyberdyne, Inc.

A frontrunner in university reform in Japan, the University is creating a flexible education and research structure as well as a university system to meet the needs of the next generation. It aspires to be a comprehensive university, continuously meeting new challenges and developing new areas. The foremost mission of a university is to provide an environment that allows future leaders to realize their full potential. The University gives students the opportunity to develop their individuality and skills through an education that is backed by cutting-edge research.

New dopamine-neuron firing pattern found



A newly discovered firing pattern of dopamine neurons in monkeys is used to evaluate rewards that vary continuously with time.

Sometimes dubbed the pleasure neurotransmitter, dopamine is a powerful neurotransmitter that plays a key role in influencing decisions. Dopamine neurons in the midbrain of an animal fire in short, sporadic pulses in anticipation of an imminent reward. But this kind of firing seems inappropriate for rewards that change moment to moment such as when heaping food onto a dog’s bowl.

Now, five researchers, all at the University of Tsukuba in Japan, have discovered a new firing pattern of dopamine neurons in two monkeys when they used colour coding to indicate a gradual increasing or decreasing level of a drink reward.

The firing pattern they observed was more sustained than the previously observed sporadic firing, making it more appropriate for evaluating rewards that change from moment to moment.
