Outline of Final Research Achievements

Choice reaction time including Stroop task was applied for the assessment of motor nerveous effects of chemicals. Hand tremor measurement was also improved to include 15～80 Hz range for the analysis. These methods including measurement of postural balance were applied for apparently healthy adult subjects. Dose-effect relationship between exhaled carbon monoxide and enlarged tremor of right hand was observed among them.
