Title
Investigation of brain activation with body schema induced by TENS using NIRS
Abstract
The body schema is a brain function to grasp own body location spatially. When a person uses tools or manipulates machines, the body schema is modified unconsciously, and he/she perceives these tools or machines as a part of his/her own body. In this study, brain activation adapting the strength of the body schema modification was investigated, and the possibility to interfere the body schema by electrical stimulus was confirmed. A tracing task (in which the participant traced characters using own hand with a stick) was designed, and the electrical stimulus was provided to the participant during the tracing task. And, cerebral blood flow was measured using near-infrared spectroscopy (NIRS) simultaneously and was analyzed. The brain activation under several conditions (the strength of the body schema modification and the strength of the electrical stimulus) was investigated using the paired t-test. The results showed that the inferior parietal lobule and the occipital lobe were significantly activated (t(8) = 1.860, p <; .05) in case of the strongest body schema modification condition. Moreover the strongest electrical stimulus had a tendency that it activated the above brain areas significantly (t(8) = 1.860, p <; .05). In consequence, it was found that the body schema modification could be induced by the electrical stimulus.
