Daiki Matsuda is a researcher specializing in motor imagery and neurorehabilitation. He holds an academic position at Fukuoka International University of Health and Welfare, Japan. His research focuses on the neural mechanisms underlying motor imagery and action observation, with particular emphasis on transcranial magnetic stimulation–based assessment of corticospinal excitability. He is also involved in developing neurofeedback approaches to support motor learning and rehabilitation. His work integrates neurophysiological measures with behavioral and subjective outcomes in rehabilitation sciences.
