Abstract

In this study, we investigated the relation between EEG signals and thermal sensation and cognitive performance. Four temperatures 26ºC, 30ºC, 33ºC and 37ºC, and two relative humidity levels 50%, 70% were examined. 32 subjects were exposed voluntarily for 175 minutes under each condition. Their EEG signals were measured, and they performed neurobehavioral tests and voted thermal and comfort questionnaires. Two indices including sensitivity and universality were proposed to determine the EEG bands and channels that best characterize the relation between EEG and thermal sensation. A linear relation was established between EEG signals and the speed of which neurobehavioral tests were completed. The results showed that P7 channel was the one that best characterized and matched the thermal sensation and cognitive performance of subjects. More measurement needed to confirm this observation.
