Device, method and program for identification of projection targets

A neuron projection target identification method that identifies one or more projection targets among K pieces (K is an integral value of two or greater) of projection target candidates with respect to predetermined projection source cells among a plurality of projection source cell candidates, comprising:

• a spike signal acquisition step of recording spike signals of a plurality of neurons at L pieces (L is an integral value of two or greater) of recording sites (R-1 to R-L) on the basis of a predetermined system;
• a projection destination stimulation step of stimulating each of the K pieces of projection target candidates as a stimulation target at a predetermined timing;
• a stimulation timing determination step of determining the priority for determining whether the detected spike signal applies to each projection source cell candidate, and determines whether or not to execute a stimulation for determining whether or not the projection source cell is a true projection target at the timing when the spike signal of the predetermined projection source cell candidate is detected, on the basis of spike signal information of the plurality of projection source cell candidates induced by stimulation to a predetermined projection target;
• a projection target determination step of determining whether or not the projection target candidates are projection targets on the basis of the spike signal information for predetermined projection source cells within a predetermined period of time before or after the stimulation when the stimulation is applied to each of one or more stimulation targets;
• and
• a priority control step of correcting the priority given to each of the plurality of projection source cell candidates on the basis of a determination result of the projection target determination unit and the spike signal information used to determine the projection target determination unit.
