We try to deeply understand human sensory and motor functions to improve these functions, using neuroimaging techniques and behavioral approaches. Our research interests cover a wide range of topics from bodily cognition to motor control & motor learning, for example, body schema (image), bodily awareness, self-awareness, action understanding, motor intention, motor imagery, motor adaptation, motor skill and sensory-motor integration. We use techniques of MRI, EEG, TMS, tDCS and behavioral apparatuses of KINARM, PHANToM, Eyelink and so on. Using brain mapping and decoding techniques, we understand human brain mechanisms underlying sensory processing, motor control & motor learning from both anatomical and functional perspectives and to promote the understanding by constructing computational models by combining behavioral measurements. Based on the systematic understanding, we develop effective methods to improve and promote human sensory and motor functions using adequate behavioral intervention, neuromodulation and neuro-feedback techniques.

Our research targets include from children, elder people, para (blind) athletes to top athletes like Neymar. By examining their brains, we challenge to elucidate principle of plasticity at brain network level through human life by visualizing functional differentiation in developing brains, functional deterioration in aged brains, and functional specialization and compensation in top and para-athletes. These researches provide an academic base for realizing a future society in which everyone from children, elderly to challenging people can enjoy their active lives by making full use of plastic adaptability implemented in our brains.

We aim to build a translational research framework where knowledge of basic science can be seamlessly applied to real-world field of physical (sport and rehabilitative) training, which can solve various sensorimotor problems especially emerging in our super-aging society. For this purpose, we are working with graduate students of Osaka University and collaborating not only with Osaka University but also other universities and companies.
