πŸͺ° A new β€˜Eyemap’ developed by a team led by Arthur Zhao & @michaelreiser.bsky.social reveals how visual information detected by the fly’s eye shows up in neurons deep in the brain. Remarkably, the eye’s shape determines how flies see motion.πŸ‘οΈ

πŸͺ°How does a fruit fly walk or fly in a perfectly straight line β€” even at high speed? It’s not just sharp vision. A sophisticated neural computation is at work.

Excited to share my PhD paper is out! We studied how motion vision is processed beyond the optic lobes to help flies walk straight. It has been a wonderful collaboration with @michaelreiser.bsky.social, @dddavi.bsky.social and many others not in bluesky!

Can you spot the difference between the cells on the left and right?

This massive effort was made possible by the incomparable Aljoscha Nern and an amazing team of experts, passionate neuroscientists, and all-around brilliant humans. πŸ™ŒπŸ’‘We all pitched in to analyze, curate, and visualize all the beautiful neurons of the fly visual system.

Excited to have this paper out (rdcu.be/d0T3Y)! In it, we focused on how flies know what to attend to in a complex environment (like below)?

We uncovered neuronal pathways through which social states (like aggression πŸ₯Š) modulate visual processing in #Drosophila. #WomenInSTEM #neuroscience πŸ§ͺ 1/

We are talking eyes, retinas, and some of the more ancestral bits of visual brains. No species restrictions. List is close to full, will start building Vol 2 before too long
