Takeshi Aihara Professor, Ph.D
My challenge is to clarify the systems in the brain related to memory and learning. In particular, I am conducting research using experimental methods (i.e., two-photon laser uncaging, optical imaging, patch clamping, and multi-electrode measurement) and theories (i.e., model simulations) to clarify memory mechanisms from the cellular to the network levels of memory information processing in the hippocampal neural network. My focus is on the effects of top-down information related to behavior and caution, and bottom-up information in the sensory system.
Yoshikazu Isomura Professor, Ph.D
When animals behave voluntarily, neurons in the cerebral cortex and hippocampus show various forms of spike activity. However, the subtypes of neurons involved and how they interact are still not completely understood. Thus, we are attempting to clarify how information that is necessary in the selection, execution, and control of behavior is sent to neural circuits in the cerebral cortex and hippocampus of rodents, using behavioral and electrophysiological methods that we established originally.
Keiko Iwata Professor, Ph.D
I am attempting to understand the children’s development and learning processes in childcare and education environments from a sociocultural point of view. While I focus on the ability of individual children to emulate behavior from brain science and developmental psychology points of view, I place more emphasis on where the emulation occurs within relationships, and where and within what type of sociocultural conditions it arises. My goal is to conduct research of events occurring on site that can ultimately be utilized in childcare environments.
Hiroyuki Okada Professor, Ph.D
I am engaged in cognitive developmental robotics research, with the aim of clarifying developmental mechanisms in human cognitive processes using infants and robots. I am interested in a wide variety of subjects, from language acquisition in infants to robot vision. My objective is to connect the seemingly unrelated fields of infant research and robotics, and understand the flexible framework of intelligence. I won the 2008 and 2010 RoboCup world championship (＠Home league), and the RoboCup Japan Open since 2008.
Yuichirou Okamoto Professor, Ph.D
The traditional understanding of "humanity" continues to change dramatically with the advancement of science and technology. How to best understand these changes as a philosophy is the central theme of my research. I approach this theme by rethinking how science and technology must exist, while attempting to understand what effect(s) these have on humans from various points of view. While my specialty is the humanities, I am conducting cross-sectional research in the social and biological sciences. In particular, I am carrying out developmental research from the biological sciences on the recently active field of "neuroethics."
Sachiyo Kajikawa Professor, Ph.D
In order to clarify language acquisition processes and mechanisms from a cognitive developmental sciences perspective, I am conducting research on infant behavior studies, as well as on observation and paper-based surveys of mother-child interaction. I have focused my attention on the relationship between phonetic perception in language and vocabulary acquisition with input from parents. In addition, I am investigating comparisons between language and music development, and characteristics of how parents sing or speak to their children. I use acoustic analysis and cardiotachometry, with attention on the role of songs in the initial stages of language acquisition.
Hiroshi Kojima Professor, Ph.D
I use the functional analysis of the central nervous system neurotransmitter receptors and synapse transmission control mechanisms to conduct reductionist research that quantitatively reveals brain functions based on experiments using electrophysiology, electropharmacology, and imaging analysis. Having worked in Western research institutions (including University College London in the UK, the Centre National de la Recherche Scientifique in France and Princeton University in the US) for 12 years, I have recognized the importance of the experience of forming amiable student-mentor relationships with instructors.

The brain is an excellent learning machine. Animals can learn appropriate behavior for various situations, although they have never experienced completely identical situation in their life. It implies that the brains can extract significant information for selection of behavior from huge sensory and stored information. The current computers can not yet do such excellent extraction of information. In order to clarify how animals can do, I am exploring the mechanisms of strange phenomena observed in brain and behavior of animals, from a view point of physics. I am tackling the unexplored topic of constructing a theoretical framework for learning mechanism of animals linking from neural systems to behavior.
Masamichi Sakagami Professor, Ph.D
I am conducting research investigating the basic neural mechanism of decision-making and thinking by combining experimental psychology and neuroscientific methods. My experimental methodology is the use of neuron activity records and functional brain imaging (i.e., fMRI). In addition, I am discussing and carrying out collaborative research with economists and philosophers on how basic brain functions related to decision-making may be linked with complicated social brain functions (i.e., neuroeconomics and neuroethics).
Tetsuhiko Sasaki Professor, Ph.D
I am investigating the development and function of brain of the European honeybee. The honeybee is a typical social insect that exhibits various social behaviors. It is surprising that they are able to carry out complicated and sophisticated behaviors using a very small brain consisting of only approximately one million neurons, which is just one ten-thousandth of the human brain. My goal is to study the framework of the simple honeybee brain at a molecular level, and clarify the relationship between the development of the brain and social behaviors.
Ryoya Saji Associate Professor, Ph.D
I am conducting developmental neurological research of infant. My goal is to gather behavioral observation surveys in the field while revealing the developmental mechanisms of the minds of infants using brain function measurement that mainly employs electroencephalogram method. I am also emphasizing pioneering educational practical activities in order to leverage the developmental neurological perspective I have gained through my research in the classroom.
Kazuyuki Samejima Professor, Ph.D
My research goal is to know the nature of the intelligence from a theoretical point of view combined with neurophysiological methods in order to investigate brain functions. How are our behavioral choices optimized, and what do neural mechanisms contribute to the process? How do we explore actions, including behavioral repertoires, in novel environments? My approach for the research is to construct a mathematical model from an information-processing perspective in order to elucidate the neural mechanisms that create intelligence, by measuring neural activity during behaving animals and comparing it with computational models.
Akira Takaoka Professor, Ph.D
Drawing on formal logic, analytic philosophy, philosophy of science, cognitive psychology, and formal linguistics, my research examines the ways we categorize musical entities of various kinds such as chords and scales and designate them in natural languages. It focuses in particular on atonal pitch organization, which still remains mostly unclear since the advent of atonal music over 100 years ago, and tries to describe rules of atonal pitch organization in abstract-algebraic terms. The development of computer programs in Java for algorithmic composition (automated composition by computers) is the creative aspect of my research.
Haruto Takagishi Research Associate, Ph.D
I am conducting research to clarify the psychological / neural basis of social behavior through experiments that combine economic games and functional brain imaging. I am also investigating the effect theory of mind have had on the development of altruistic behavior and sense of fairness via developmental psychology experiments with preschoolers and elementary school students.
Tetsuya Matsuda Professor, Ph.D
I am conducting research related to the neural mechanisms of social decision-making using functional brain imaging, as well as psychological and physiological methodologies. First, I examine these mechanisms with basic neuroscience; then I take an approach that connects these findings with clinical research. In my clinical research, I investigate the relationship between the pathology of mental disorders and social decision-making impairment.
Kenji Matsumoto Professor, Ph.D
My challenge is to clarify the neural mechanisms of human agency from the view of goal-directed behavior, value representation, and motivation, by combining functional brain imaging with educational and social psychological methodologies. Some of my groundbreaking findings are highly regarded internationally.
