Sign-Inverting Vectors Underlie a Coordinate Transformation in the Drosophila Central Brain
… dissertation focuses on a system of neurons that signals wind direction in the Drosophila central brain. We found that the activity of these neurons, called PFNa, can be thought of as a set of vectors whose summed activity yields the direction of wind in an allocentric reference frame — that is, …

A Neuronal Circuit Architecture for Angular Integration in Drosophila
… many animals keep track of their angular heading over time. However, a neuronal-circuit architecture for computing heading remains unknown in any species. In this thesis, I describe a set of neurons in the Drosophila central complex whose wiring and physiology provide a means to shift an …

Spontaneity and Precision in the Drosophila Central Nervous System
… goal-directed navigation, animals may use stored heading and distance signals to travel efficiently to a desired location. This thesis explores the circuitry underlying these disparate navigational strategies in Drosophila. I first show that normal synaptic transmission in a genetically specified …
