So excited to have received an #HFSPResearchGrant to study trilobite eyes with Luke Parry @oxuniearthsci.bsky.social and Gil Ju Lee (Pusan National University)!🥳 I'll be recruiting a postdoc @bristolbiosci.bsky.social - if 3D data, optical modelling, and fossils tickle your interest, stay tuned!

Thank you all! Also big thanks to @russellgarwood.co.uk and experienced HFSP-ers @mikebok.bsky.social, Dan Speiser, and Carsten Lüter for their advice on the proposal 💛

From our new paper out now in @currentbiology.bsky.social: www.cell.com/current-biol... w/ @neurofishh.bsky.social @gkafetzis.bsky.social @denilsson.bsky.social Looking across animals, the vertebrate eye is an obvious outlier. Why is it so different that other highly visual animals?

My collaborator at University of Copenhagen, Anders Garm, is looking for a 3 year postdoc to work on bioluminescence, neurobiology and ecology of ctenophores. More information here: candidate.hr-manager.net/ApplicationI...

Ever wanted to know how the visual system of a long distance migratory moth looks like? Then you'll find your answers in our new paper. Finally out, after about a decade of collecting data by a group af amazing co-authors. Find it here, open access: link.springer.com/article/10.1...

Thanks so much to ASAB and the #ASABwinter2025 organisers for a cracking conference. Not sure why I’m so excited here, I guess the yoghurt and granola had just been served…

Very excited about our new preprint, led by @gkafetzis.bsky.social /w @mikebok.bsky.social & @denilsson.bsky.social. We suggest that the vertebrate 'duplex' retina emerged from interconnecting two ancient median-eye microcircuits. Say goodbye to the 'simplex' retina - it probably never existed!

Most bilaterians keep photoreceptor types separate. But vertebrate eyes are a mash-up: 🪡Ciliary (rods & cones) and 💈Rhabdomeric (ganglion, amacrine, horizontal) …all packed into a multilayered circuit. 2/n

👁️The retina — strikingly conserved across vertebrates, but an oddity among bilaterians! So how did it evolve? With @mikebok.bsky.social, @neurofishh.bsky.social and @denilsson.bsky.social, we argue that retinal complexity may 𝑝𝑟𝑒𝑑𝑎𝑡𝑒 𝑡ℎ𝑒 𝑒𝑦𝑒 𝑖𝑡𝑠𝑒𝑙𝑓. www.biorxiv.org/content/10.1... 1/n

Very excited and proud to finally share this story! 🐙 We discovered surprising roles for dopamine and acetylcholine in the Octopus visual system… doi.org/10.1101/2025...

Super excited to have received a @hfspo.bsky.social grant with with @neurofishh.bsky.social for our proposal: Eyes inside out: Visual coding without a multilayered retina in squid and worms.

oh INTERESTING! So apparently this FOUR EYED thing is a consistent anomaly cross different strombid taxa ?!?#molluscmonday www.inaturalist.org/observations...

An"eye-catching" talk by Mike @mikebok.bsky.social from the Lund Vision group @lundvision.bsky.social at @univie.ac.at @viennabiocenter.bsky.social today, cutting from fan worm eyes to the gollum-like eyes of alciopid worms (see the recent @currentbiology.bsky.social study: doi.org/10.1016/j.cu...)

Two blue mosquitoes (there are more!). Left, Toxorhynchites (a worldwide genus whose larvae are predators on other aquatic insects including mosquitoes) and right, Sabethes, a South America genus where adults have large patches of scales on their legs for sexual display. #BlueMonday #BlueBugs

Just started reading this exciting book edited by @mikebok.bsky.social & Elke Buschbeck. It takes us to a fascinating world on different visual systems featuring evolutionary and behavioral aspects. A must read for everyone interested in #neuroethology & vision. link.springer.com/book/10.1007...

I'm very excited to give this talk in January! It's free to attend via zoom if you're interested! :)

This is so sad. The first image on Google search for the firefly squid is AI slop of god-knows what...

Gap junctions FTW! If you want to understand how neuronal circuits work, you can’t ignore gap junctions.

At depths over 6,000 meters, researchers have discovered “faceless” fish with no visible eyes or nose, relying on unique sensory adaptations to navigate in complete darkness. #marinelife

Pure autofluorescence from the midband crystalline cones in a mantis shrimp eye. The fluorescence comes from mycosporine like amino acid pigments that absorb specific bands of UV light, thus tuning the UV sensitivity of the photoreceptors they focus light into. 🧪 #FluorescenceFriday
