Short Communication



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.


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 eachALDH2 genotype.


Different hemodynamic changes in the motor cortex were observed among, theALDH2 genotypes.


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.

Key words
