Evolution of odor coding and circuits in a human- biting mosquito
A domestic form of the mosquito Aedes aegypti has evolved a robust preference for human body odor within the past 5K years — providing a remarkable example of how natural selection can rapidly reshape neural circuits to maintain appropriate responses to sensory information. I will discuss our recent work trying to understand the neural basis of this shift. I will also discuss our characterization of a complete olfactory receptor-neuron map for this species based on sequencing of over 45K neuronal nuclei from female antennae. Our map provides important updates to recently published work on receptor co-expression and uncovers a novel phenomenon involving combinatorial molecular coding at the receptor expression level.
