“…The question arises, however, about which abstraction level, with respect to relevant physiological mechanisms, is adequate for the purpose of estimating autonomic influences on cardiovascular control. In our opinion the abstraction level of, for instance, the already refined model of Luczak and Ohsuga (Ohsuga, Terashita, Shimono, & Toda, 1995) is still too high for this goal.…”

A quantitative baroreflex control model is presented aimed at estimating differences in autonomic activation due to mental task performance. The model, which builds on earlier work of Wesseling and colleagues, is strongly supported by well‐established knowledge of physiological control processes. Spectral measures of heart rate and blood pressure variability provide the information to estimate autonomic gain and tone parameters. The article gives a detailed model description as well as an evaluation in terms of spectral variability distributions, respiratory sinus arrhythmia, and vagal control mechanisms. The estimation procedure is outlined while presenting two studies that describe the effects of mental workload and vagal blockade, respectively. It is concluded that, using the model approach, cardiovascular effects of mental task performance can be interpreted in terms of specific changes in autonomic state. The model is implemented in a Matlab/Simulink environment and is available for other researchers in the field.

“…Although the effect of aroma on physiological and psychological state of living body, and the mechanism of that effect were studied by some researchers [2,3], almost all the aroma studies on the central nerves system were investigated by the electric physiological changes in aroma presentation [4]. With respect to the evaluation of specific work stress and mental fatigue, the studies measuring the plethysmogram and electro-cardiogram as an index are reported [5][6][7][8]. However, the studies with respect to the effect of aroma have been few.…”

We investigated the effect of aroma on the event related potential (ERP) during certain cognitive workload. In this study we regard repeated oddballtask as our cognitive woridoad, while the oddball task itself is used to be considered as the cognitive task for investigating the event related potential under the auditory stimuli. We used the oddball task consisting of three kinds of tones. The oddball task used in this study was consisted of three kinds of auditory stimuli. The auditory oddball operation task was 8 min long and a total of three tasks were conducted twice at 3 min intervals. The latency of P300 during the third task of the oddball operation increased more than that of the first task. The delay of the P300 latency was thought to be related to the mental fatigue induced from the auditory oddball task. The effect of aroma on the mental fatigue induced from the auditory oddball task was studied using the aroma of lavender, rose and lemon. It was found that the delay of the P300 latency was shorter in the presence of aroma (lavender, rose and lemon) than that without the aroma These results would suggest that the presence of an aroma could be effective in reducing mental fatigue induced from the auditory oddball task.

“…Furthermore, Ohsuga et al (1994) introduced a closed-loop model based on Luczak's model, which was introduced in 1975. The modifications introduced to the original model include the mental load and the optimisation of the constants within it.…”
