A biological function measurement and analysis system, a biological function measurement and analysis method, and a recording medium storing program code causing a computer to execute the biological function measurement and analysis method. The biological function measurement and analysis system includes an input acceptance unit configured to accept selection of a biological function to be measured, and a measurement and analysis procedure determining unit configured to access a memory in which measurement and analysis procedure data, indicating a combination of measurement and analysis of reaction of a live subject caused by stimulation on a biological-function-by-biological-function basis, is stored to specify measurement and analysis procedure data corresponding to the selected biological function. The biological function measurement and analysis method includes accepting the selection of biological function to be measured, accessing the memory, and specifying the measurement and analysis procedure data corresponding to the selected biological function.

A biological information measuring apparatus includes a cover member and a hardware processor. The cover member is provided with sensors for detecting biological signals to cover a position of a biological part of a subject. The hardware processor is configured to estimate a positional relation of the position of the biological part of the subject with respect to the cover member at a first time point. The hardware processor superimposes first point cloud and second point cloud. The first point cloud is acquired by a non-contact mechanism front the subject at the first time point and represents a surface of the biological part of the subject in a coordinate system of the sensors. The second point cloud is created based on a morphological image of the subject captured by a biological structure acquiring apparatus and represents the surface of the biological part of the subject.

A biological information measurement system includes a dewar, a single imaging device, and a hardware processor. The dewar covers a head of a subject and contains sensors that are arranged for detecting biological signals. The single imaging device acquires an image in which three or more reference points and the dewar are captured, the reference points being set in relation to the subject. The hardware processor is configured to: measure brain neural activity of the subject based on the biological signals detected by the sensors; determine positional relationships between the reference points of the subject and the sensors based on the reference points and positional relationship data of the dewar; and re-determine the positional relationships between the reference point of the subject and the sensors, based on images that are acquired by the single imaging device at different times.
