Cross-species connectome comparison shows uneven olfactory circuit evolution in flies

The findings start to reveal evolutionary changes that may have helped two species develop different olfactory preferences and adapt to their particular environments.

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.

Cephalopods, vision’s next frontier

For decades, scientists have been teased by the strange but inaccessible cephalopod visual system. Now, thanks to a technological breakthrough from a lab in Oregon, data are finally coming straight from the octopus brain.

International scientific collaboration is more necessary—yet more challenging—than ever

These partnerships accelerate neuroscience by enabling researchers to share resources and expertise, as well as generate more relevant and reproducible results. But new federal funding restrictions in the United States are putting such collaborations in jeopardy.
