Device, method and program for identification of projection targets

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 unitacquires spike signals generated from multiple neurons existing in the vicinity of two or more recording sites. A stimulation control unitselects 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 unitacquires 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 unitacquires and manages information relating to the anti responses. A collision response management unitacquires and manages information relating to the collision responses. A priority control sectioncorrects and determines priority depending on the anti response information and the collision response information.
