An interesting commentary by Jordanna Sprayberry on our recent @pnas.org paper (pinned on my profile) showing lateralized visuomotor control in hawkmoths 👁️🥤🦋 Cool to discuss additional context of neural circuit structure and ultimate consequences for such control axes www.pnas.org/doi/10.1073/...

To see, or not to see: fruit flies selectively suppress visual input via electrical transmission of an efference copy

Thank you @sercansayin.bsky.social for involving us in this study, which teaches us locusts care about looks, and won't march with just anyone! Featuring modelling of locust vision by @gkolyfetis.bsky.social 🪳👁️🤖🧪

Congratulations to @ashritocyte.bsky.social on an amazing PhD defense! 🎓🐟 Ashrit uncovered structure in zebrafish behavioral variability, showing how past decisions influence what fish do next. He also shaped lab life, from cooking and game nights to chats and teaching. We wish him the best of luck!

New preprint! www.biorxiv.org/content/10.6... Nearly a decade after starting the project, the first major results from our comparative connectomics work is online! Comparing the head direction circuits of the central complex in bees, ants and flies, recapitulating >300million years of evolution.

New paper from the lab 🎉🚨 We found that hummingbird hawkmoths show lateralised proboscis control on both the sensory and motor sides. 🦋 How plastic is this lateralised visuo-motor axis when sensory input is perturbed? Find out more 👇

🚨🦋 Thrilled to share my first PhD paper published in PNAS this week, in collaboration with Sören Kannegieser and @anna-stoeckl.bsky.social @insect-vision.bsky.social: www.pnas.org/doi/10.1073/... We found hawkmoths use a convergent visual control strategy for appendage guidance. 👁️🫳 🧵 below.

What a great start to the summer with @elefp.bsky.social and @syddoingscience.bsky.social representing the lab at the Neural Basis of Natural Behaviors conference!🧠 From worms to humans, the talks reflected an exciting new direction in neuroscience toward studying the brain in natural environments.

I am thrilled to share my second PhD manuscript! We modelled bee polarisation vision and tested two navigational models. Many thanks to @jjfosterlab.bsky.social and all our collaborators (@egkanias.bsky.social,@edinburgh-uni.bsky.social,@insectlabsu.bsky.social) for such a productive collaboration!

Do bright lights change how you dance? 🔆💃 Waggle-dancing honeybees interpret bright UV & green as the sun, but dim UV as a patch of sky. Thanks Keram Pfeiffer @uni-wuerzburg.de for trusting me with your data & @jgraving.bsky.social for the circular GLMM. doi.org/10.21203/rs....

We're making a new WhereDoGGo logo. After discussions, we decided to stop using the ASCII art representation of a certain Shiba Inu. Please send us portraits of your doggos, so we can generate a new logo. The plan is to rotate with every major version.
