Somatosensory Evoked Potentials, and Electroencephalography
Conditions
Brief summary
The purpose of this study is to examine the functional and structural modification effects on the brain of a non-invasive experimental device applied to the head and forearms of healthy subjects during motor recall training. The experimental device used in this study is the Brain-Machine Interface (hereinafter referred to as BMI), which is under development in the principal investigator's laboratory. The BMI consists of an arithmetic unit that processes the results in real time using a personal computer, a depth ray that displays the results, a transcutaneous electrical stimulator that is driven based on the results of the arithmetic, and an exoskeletal motor assist device that is driven based on the results of the arithmetic.
Detailed description
This study does not fall under the category of 'medical research involving human subjects' or 'clinical research subject to legal regulations' in Japan, and the appointment of a principal investigator (PI) is not required. For the convenience of registry submission, the name of the principal investigator field has been filled with the name of the study representative (a non-physician).
Interventions
BEHAVIORALNeurofeedback
The participants received visual feedback of the processed result of neural signals acquired online.
BEHAVIORALSham-feedback
Previously recorded neural signals are processed and presented to participants as if the signals from them are processed online.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Somatosensory evoked potential | From the timing of pre-training evaluation (before the intervention) to the end of evaluation (after the intervention), with the intervention lasting 30 minutes. | Median nerve stimulation elicits the somatosensory evoked potentials. Their amplitude was calculated. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Touch typing performance | From the timing of pre-training evaluation (before the intervention) to the end of evaluation (after the intervention), with the intervention lasting 30 minutes. | A touch typing task was employed to test sensorimotor integration performance |
