Neuronal activity underlying vocal production in bats. [PDF]

open access: yesAnn N Y Acad Sci
Bats are known for their highly evolved echolocation and social vocalizations. They have been well studied in terms of auditory processing, but their neural circuits for vocal production are far less understood. This review highlights recent progress in mapping neural activity linked to vocalization in bats.
