Davide Raccuglia conducted the work for this paper while in the department of cellular and molecular physiology at Yale University School of Medicine. He is currently a research scientist at the Institute of Neurophysiology at the Charité in Berlin, Germany. Raccuglia studies how the integration of different neurotransmitter inputs and their receptors modulates neuronal activity in the brain of the fruit fly, Drosophila melanogaster. He uses recently developed genetically encoded voltage indicators that allow for optical electrophysiology of multiple cell bodies simultaneously and neurites too small for classical electrophysiology. The goal is to deepen the understanding how differential synaptic inputs and their corresponding neuronal activity modify essential behaviors such as locomotion, sleep, and learning.
