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.

Systems and circuit neuroscience need an evolutionary perspective
To identify fundamental neuroscientific principles that generalize across species, neuroscientists must frame their research through an evolutionary lens.

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.

How ‘walking fish’ feel, taste hidden food with their legs
Fins-turned-legs in sea robins are innervated with touch-sensitive neurons and taste-receptor-rich cells that can detect prey buried in the sand, according to new research.

Worms help untangle brain structure/function mystery
The synaptic connectome of most animals bears little resemblance to functional brain maps, but it can still predict neuronal activity, according to two preprints that tackle the puzzle in C. elegans.
