Naofumi Suematsu is interested especially in sensory processing and sensory prosthesis. Currently he is working on the assessment of the responses induced by the intracortical microstimulation and comparing with naturally-evoked activities with combining multiple imaging techniques such as two-photon Ca microscopy, macroscopic imaging, and optical intrinsic signal imaging. His ultimate research goal is to develop more neuro-morphic and neuro-compatible prosthetic devices.
