Objectives: To use the evaluation of a specific brain function obtained by optical topography. This system uses a non invasive method to measure brain function, unlike other major systems.<br> Methods: Twelve optical fibers were attached to the subject's head. Hemodynamic changes in the motor cortex were measured during finger tapping before and after alcohol intake for each ALDH2 genotype. <br> Results: Different hemodynamic changes in the motor cortex were observed among the ALDH2 genotypes.<br> Conclusions: Optical topography is a useful tool for evaluating specific brain functions. Further research is needed on the relations between various environmental factors and brain functions by optical topography.<br>
