Genes, Circuits, & Behavior
We aim to understand the genetic and neural basis of brain functions in Drosophila. Our missions are: (i) to construct a wiring diagram of the entire fly brain; and (ii) to understand the design of individual circuits for both innate and learned behaviors.
Wiring diagram. We have generated a standard Drosophila brain for archiving and analysis of individual neurons. We are currently trying to construct (i) a mesoscopic map showing connections between different neuropilar regions; and (ii) a map of synaptic connectivity amongst olfactory neurons.
Brain functions. Our focus is on understanding circuits and genes involved in olfactory, auditory, gustatory, sleep, courtship, fighting, aging, fear, and learned behaviors.
