Song Patterning and Production
In spite of its fundamental importance to communication, we know surprisingly little about how sensory cues modulate acoustic patterns in real time. We have recently demonstrated that, unlike most other insects and even some songbirds, flies sing highly variable songs (from one bout to the next, even within individuals). However, using a simple computational model combined with neural circuit manipulations, we demonstrated that the dynamic sensory experience of the male accounts for much of this variability. In particular, male flies rely on fast modulations in visual and self motion cues to pattern the structure of individual song bouts. The long-term objective of this line of research is to understand the cellular mechanisms by which time-varying sensory information is integrated into individual neurons of the song motor circuit. To do this, we combine quantitative behavioral assays, genetic and neural circuit perturbations, and in vivo neural recordings.
