Abstract Echolocating bats exhibit remarkable auditory behaviors, enabled by adaptations within and outside their system. Yet, research in echolocating has focused mostly on brain areas that belong to the classic ascending pathway. This study provides direct evidence linking cerebellum, an evolutionarily ancient non-classic structure, vocalization hearing. We report fruit-eating bat Carollia perspicillata , external sounds can evoke cerebellar responses with latencies below 20 ms. Such fast are indicative of early inputs cerebellum. In vocalizing bats, distinct spike train patterns allow prediction over 85% accuracy sound they about produce, or have just produced, i.e., communication calls echolocation pulses. Taken together, our findings provide specializations for hearing cerebellum specialist. Teaser The responds predicts future past vocalizations
