Neural tuning for species-specific acoustic signals is a conserved feature of auditory systems – it is found from insects all the way to humans. However, the precise mechanisms involved remain mysterious. We take advantage of the tools available in Drosophila to investigate, at the level of individual neurons and patterns of electrical activity, how such tuning arises and how it relates to behavioral decisions.
We record neural activity along the auditory pathway and in response to sounds (both natural and synthetic), starting with mechanosensory neurons in the antenna (or ear of the fly) all the way to central brain regions. Using computational modeling, we can discover how neural codes relate to behavioral preferences for song.
