The authors conducted neurometory of 78 so-called healthy adults throughout the year. Electrical skin resistance (amperage) was measured at the representative measurement points of the ryodoraku. In order to clarify how this resistance changes with months and which ryodoraku is related to the comparison of month groups, the results were analized using discriminatory analysis which is one technique of multivariate data analysis. The primary discriminant function explained the fluctuation of 63.7%, and is related to the ratio of H4 and H6 to F4. The secondary discriminant function explained the fluctuation of 20.2%, and is related to the ratioI of F2 and F4 to H2. In the second-dimensional distribution, the cold season group (April, November, December, January) was against the warmIseason group (June, July, September), and intermediate season group (May, October). However, April wasjrather specific, that is, apart from the other cold seasons. Further observations must be done with regard to seasonal fluctuation.
