Description

We’re susceptive to the effects of psychological stress on our autonomic nervous activities, and symptoms including dysautonomia develop if the degree of stress is high. Hence, we conducted a frontal lobe test as a stress tolerance test and the changes in the autonomic nervous activities were determined by heart rate variability to evaluate its effects in the frontal lobe on the autonomic nervous activities. As a result, CVRR values were classified into ２ types, one type in which high CVRR values before the initiation of the test decreased at the initiation, and the other type in which low CVRR values before the initiation increased at the initiation. Furthermore, responses varied with the types of frontal lobe tests : LF and LF/ HF values decreased in a Stroop test, while LF/HF values were higher in a WCST compared with the Stroop test. These data indicate that Stroop test may be used as a psychological stressor.
