title: Application of specific brain function evaluation by optical topography.
abstract: OBJECTIVE
  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.
  
  
  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 eachALDH2 genotype.
  
  
  RESULTS
  Different hemodynamic changes in the motor cortex were observed among, theALDH2 genotypes.
  
  
  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.
