在狩猎过程中，持续时间的选择性和恢复周期是蝙蝠确定回声持续时间和目标距离（回声测距）的能力的基础。本研究表明，大多数持续时间选择性神经元的蝙蝠中央核下丘神经元的恢复周期不同的生物相关的脉冲回波（P-E）的持续时间和振幅。因此，当用短时程和小P-E幅度差的P-E对刺激时，最佳时程短的神经元恢复迅速，而当用长时程和大P-E幅度差的P-E对刺激时，最佳时程长的神经元恢复迅速。这些数据表明，不同群体的持续时间选择性神经元的蝙蝠的能力，有效地执行回声识别和测距在不同阶段的狩猎。
During hunting, duration selectivity and recovery cycle underlie a bat's ability to determine echo duration and target distance (echo ranging). This study shows that the recovery cycle of most duration-selective neurons in the bat central nucleus of the inferior colliculus neurons varies with biologically relevant pulse–echo (P–E) duration and amplitude. As such, neurons with short best duration recover rapidly when stimulated with P–E pairs with short duration and small P–E amplitude difference, whereas neurons with long best duration recover rapidly when stimulated with P–E pairs with long duration and large P–E amplitude difference. These data indicate that different groups of duration-selective neurons underlie the bat's ability to effectively perform echo recognition and ranging during different phases of hunting.
