Outline of Final Research Achievements

① Development of a method to experimentally reproduce thermal discomfort, ② Development of a method to reproduce ① in the brain function imaging device (fMRI) and obtain brain function image. Hypothesis verification that temperature sensation sensation and thermal discomfort feeling are processed in different brain regions. ③ Eluciation of the mechanism of transformation of thermal discomfort seen during exercise and dehydration from the changes in deep body temperature and skin temperature. For ①, regional temperature difference of the body surface can be reproduced by constructing it by a combination of rise and fall of body surface skin temperature with water perfusion suit and local skin temperature stimulation. ② Different brain regions were involved in temperature perception (discriminative and hedonic components). ③ Possible contribution to the thermal discomfort feeling other than the temperature parameter per se was clarified.
