We have inspected that correlation dimension analysis of electroencephalograms (EEG) was useful as a method for evaluating thermesthesia objectively. EEGs were recorded with ten Ag-AgCl electrodes affixed to the subject's scalp with and without clothes in the chilly environment. The correlation dimension of EEG without clothes was significantly smaller than with clothes. This result agreed as a result of sensory test for thermesthesia. There was no significant among ten electrode placements. From these results, we conclude that the correlation dimension would appear to be a criterion to describe thermesthesia.
