The striatum neurons showed a residual firing response of slowly increasing duration when exposed to repetitive optogenetic photostimulation. The prolonged firing resumed after a 20 sec intermission. Residual depolarization with 8-sec half-life decay and firing prolongation by the repetitive photostimulation were observed through whole-cell patch clamp recordings. Our results indicate that striatal neurons hold their internal state in second-order timescale to count inputs cumulatively. Moreover, we proposed a new reinforcement learning model which was inspired by the prolonged firing.
