Interesse da Investigação

We are interested in the nature of defined neural circuits: how activation of circuits elicits specific behaviors. Animals exhibit behavioral repertoires that result in stereotyped sexual and social responses to their environment. Innate behaviors do not require learning or experience and are likely to reflect the activation of developmentally programmed neural circuits. It has been extremely difficult in complex organisms to study a circuit beyond the early stages of sensory processing. We have been using Drosophila melanogaster because flies exhibit complex behaviors that are controlled by a nervous system that is numerically five orders of magnitude simpler than that of vertebrates making it an attractive model system to understand a circuit. We use a combined behavioral, genetic, imaging and electrophysiological approach to determine how defined neural circuits and their activation elicit specific behaviors.
