This paper changed my life: Bradley Dickerson on how a 1940s fly neuroanatomy paper influences his research to this day

This classic paper by zoologist John Pringle describes the haltere—a small structure in flies that plays a crucial role in flight control. It taught me to think about circuits and behavior as greater than the sum of their parts.
