Researchers in our department have a variety of backgrounds including medicine, science, life science, engineering, pharmacy, linguistics, pedagogy, and the arts, and work energetically on a wide range of studies of brain science, from the basic brain research in small animals (e.g., rats and mice), to functional brain imaging research, which creates images of the working of the mind, to social technology study, which applies the findings of these studies to educational and welfare fields.
In basic brain research in small animals, we try to combine the invasive techniques such as post-mortem histology, genetic manipulations, and pharmacological interventions, in order to clarify the underlying biological mechanisms behind the human neuroimaging findings.
In functional brain imaging research, our interest is the "human mind." We elucidate the neural underpinnings of cognitive functions, such as perception, memory, motor, linguistic, and emotional processes, and reveal the mechanism of the mind that survives the complicated physical and social environment around us.
In social technology research, we will open a new possible approach to education and social welfare from the viewpoint of brain science. We develop welfare systems for the improvement and maintenance of brain function in the elderly and education systems to best foster the healthy development of brain function in children.
