Claim 7:
8. A non-transitory computer-readable recording medium of an apparatus storing a program that causes a processor to execute a process, the process comprising:
acquiring, for each of one or more electrodes disposed in one or more chambers, a potential of each of at least one measurement electrode of the one or more electrodes at one or more predetermined times, wherein the apparatus comprises a culture vessel that includes a partition member disposed on a bottom wall of the culture vessel, wherein the partition member includes the one or more chambers, wherein one or more electrodes are disposed in the one or more chambers, wherein each of the one or more electrodes are composed of at least one reference electrode and a at least one measurement electrode that are disposed about a partition wall that separates the one or more chambers from each other;
determining at least one principal component for each of the at least one measurement of the one or more electrodes by performing principal component analysis of the potential for each of the at least one measurement of the one or more electrodes at the one or more predetermined times;
estimating, for each of the at least one measurement electrode of the one or more electrodes, a principal component potential corresponding to the principal component from the principal component of the at least one measurement electrode of the one or more electrodes; and
synthesizing the estimated principal component potential of each of the at least one measurement electrode of the one or more electrodes;
subtracting the synthesized estimated principal component potential of each of the at least one measurement electrode of the one or more electrodes from the potential acquired for the at least one measurement electrode of the one or more electrodes so as to remove noise; and
outputting a potential difference based on theater subtraction that reflects an activity of an object in the culture vessel.
