Bio-optical measurement data analysis apparatus, analysis method, and program therefor

摘要

A brain activity signal from which noise has been removed is derived from a biological optical measurement signal including a noise signal without complicating the device configuration. In the biological optical measurement data analyzing apparatus and analyzing method, the brain activity signal corresponding to repeated experiment tasks shows the same signal change with each repetition and the oxygenated hemoglobin concentration change signal which is the brain activity signal and deoxygenation And the hemoglobin density change signal are inversely correlated with each other, a signal obtained by multiplying each signal obtained from a plurality of measurement regions observed almost at the same time by a weighting factor optimized for each brain, As an activity signal component.
