"Neural Circuits for Vocal Communication: Insights from the Singing Mice."
My long-standing interest is to understand how circuits of interacting neurons give rise to natural, adaptive behaviors. Using vocal communication behavior across rodent species, my lab at CSHL pursues two complementary questions. How does the auditory system interact with the motor system to generate the fast sensorimotor loop required for vocal communication? What are the neural circuit modifications that allow behavioral novelty to emerge during evolution? In this talk, I will introduce you to the rich vocal life of the Costa-Rican singing mice. Next, I will describe a series of experiments that were performed to demonstrate the role of the motor cortex in controlling vocal flexibility in this species. In closing, I will discuss our ongoing efforts to identify neural circuit differences between singing mice and lab mice using high-throughput connectomics. Together, by combining neural circuit analysis of a natural behavior with comparative evolutionary analyses across species, we stand to gain insight into the function and evolution of neural circuits for social behaviors.
