I received my PhD in Neuroscience in 2017 from the University of California in San Francisco. Practically all animals move, and locomotor behaviors coincide with, or even cause, widespread changes in neural activity. This poses the question: how do neural circuits function under such different conditions to execute coherent behaviors? I address this question by studying how locomotion modulates neural circuit dynamics and behavior in a genetically tractable system, the fruit fly D. melanogaster.
