Application of specific brain function evaluation by optical topography

ABSTRACT

<p><b>OBJECTIVES</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>Different hemodynamic changes in the motor cortex were observed among, theALDH2 genotypes.</p><p><b>CONCLUSIONS</b>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.</p>
