Inclusion criteria

Inclusion criteria: 1) 20 to 30 years old, 15 males and 15 females 2) Persons belonging to the Department of Health Sciences, Gunma University School of Medicine, or the Graduate School of Health Sciences, Gunma University 3) Healthy subjects with no disease currently under treatment 4) Persons who can give written consent to participate in this study.

Design outcomes

Primary

Measure	Time frame
A heart rate variability real-time analyzer (MemCalc/Bonaly Light: GMS) is attached to the subject. After 5 minutes of measurement in a resting sitting position, 5 minutes of word memory, followed by 5 minutes of rest, the test is performed for 10 minutes, during which time autonomic nerve activity is measured. In the heart rate variability analysis, the Low Frequency (LF, low frequency, and High Frequency (HF, high frequency, 0.15-0.40 Hz band) components are extracted as changes in autonomic activity, the HF component is cardiac vagal activity, and the ratio of both components (LF/HF) is an index of cardiac sympathetic nerve activity. These measures are compared with the results of the VAS scale responses in the questionnaire and the performance in the post-memorization exam to examine the relevance of these measures.	—
