Recovery Cycle of Single-on and Double-on Neurons in Inferior Colliculus of CF-FM Bat

【摘要】：正The bats scan the surrounding and hunt insects by emitting continuous sequences of echolocation signals.It is very important for echolocation bats that the recovery cycle of central auditory neurons can determine the responses of neurons to second sound stimulation. For constant frequency-frequency modulation (CF-FM) bats,there is some overlap between emitted sound signal and echo under anyhow low or high pulse repetition rate condition. But the CF-FM bats still can extract information from echo and discriminate the target from the background much better. Therefore,it is a very interesting question that how CF-FM bats can be against the overlap between emitted sound signal and echo.
