The human brain consolidates various pieces of information about the mind and body and then deploys these pieces of information into action. When brain function is disrupted, a wide range of problems appear in the mind and body.

In order to examine these problems, we at Kodama’s laboratory (TK-Lab) conduct component and frequency analyses using non-invasive brain function examinations (i.e. quantitative electroencephalogram analyses). We also use applied brainwave imaging analyses (i.e. LORETA, microtate segmentation analysis, Livo, EEGLAB, etc.), autonomic nervous system analyses, and saliva biomarkers to examine these problems from the perspective of neurophysiology, particularly as it relates to rehabilitation.

Through these experiments, we aim to establish protocols for neurological rehabilitation to assist in the redevelopment of neural function in people with impaired brain function.
