  • Patent number: 11685884
    Abstract: The purpose of the present invention is to provide a technique whereby multiple projection targets are efficiently identified from multiple neurons in multiple brain areas with the use of multis-point light stimulation. An acquisition unit 52 acquires spike signals generated from multiple neurons existing in the vicinity of two or more recording sites. A stimulation control unit 51 selects one projection target candidate from two or more candidates in accordance with a definite system on the basis of the spike signals and then determines irradiation timing of light stimulation. Upon the light stimulation, a management unit 53 acquires the spike signals in all of the recording sites within a definite period of time before or after the light stimulation, while dividing the spike signals into anti responses and collision responses. An anti response management unit 81 acquires and manages information relating to the anti responses.
