Abstract: An information processing device, an information processing method, a recording medium storing a program, and a biomedical-signal measuring system. The information processing device includes circuitry to obtain specific information of a first intensity distribution of a biomedical signal from a source, the specific information being displayed on a display, and extract, based on the specific information, a specified area of the first intensity distribution to obtain second intensity distribution of the biomedical signal to be superimposed on an image indicative of the source. The information processing method includes obtaining specific information of a first intensity distribution of a biomedical signal from a prescribed source, the specific information being displayed on a display, and extracting, based on the specific information, a specified area of the first intensity distribution to obtain second intensity distribution of the biomedical signal to be superimposed on an image indicative of the source.

Abstract: An information processing apparatus includes a display controller configured to group dipole estimation results with the same direction out of dipole estimation results of a signal source corresponding to part of biological data indicating a chronological change of a biological signal and display the grouped dipole estimation results in a manner superimposed on a plurality of biological tomographic images sliced in a predetermined direction. The display controller is configured to, when displaying a non-grouped dipole estimation result, display the non-grouped dipole estimation result in a different color or form from a color or a form of the grouped dipole estimation results depending on a direction of the dipole estimation result.

Abstract: An information processing device, an information processing method, a recording medium storing a program for causing a computer to execute the information processing method, and a biomedical-signal measuring system. The information processing device includes circuitry to control a display to superimpose a first image indicative of an estimated site or portion of a live subject on a biological image of the live subject, and control the display to superimpose a second image indicative of a result of analysis on the biological image. The result of the analysis indicates activity of the live subject. The information processing method includes controlling a display to superimpose a first image indicative of an estimated site or portion of a live subject on a biological image of the live subject, and controlling the display to superimpose a second image indicative of a result of analysis on the biological image.

Abstract: A measuring device includes a stimulation instructing unit and an estimating unit. The stimulation instructing unit is configured to instruct a stimulating device to generate a plurality of stimulations corresponding to at least three fiducial points of brain anatomy data, the at least three fiducial points having been defined in the brain anatomy data. The estimating unit is configured to estimate, based on sensor output signals output from sensors configured to measure a brain activity signal of a subject who is a target to be measured, parts where brain activities occur due to the plurality of stimulations.

Abstract: A biological signal analysis device includes: an acquiring unit configured to acquire biological signals of a measurement target; a trigger information acquiring unit configured to acquire, from a stimulator configured to apply stimuli to the measurement target, trigger information indicating times at which the stimuli are generated; and a signal processing unit configured to process the biological signals. The signal processing unit is configured to calculate biological information on the measurement target based on the biological signals, maintain only pieces of trigger information corresponding to times at which it is determined that biological signals of the measurement target are generated, from the calculated biological information, delete another piece of trigger information, and use an averaged waveform that is obtained by performing an averaging process on the biological signals that are generated in synchronization with the stimuli based on the pieces of remaining trigger information.

Abstract: 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.
