Looking for weekend reading? New review by @kei-jokura.bsky.social and @jekely.biologists.social.ap.brid.gy revisits nerve nets, their functional organization, and evolutionary implications link.springer.com/article/10.1...

What is the evolutionary origin of the organizer? New work from @kremnyovs.bsky.social, @tclebedeva.bsky.social & Hejnol Lab @uni-jena.de reports the blastopore lip of the #ctenophore Mnemiopsis leidyi, a member of the evolutionary sister group to all other metazoans, exhibits organizer activity.

A blastoporal organizer in a ctenophore - Nature

Experiments using the comb jelly Mnemiopsis leidyi and the sea anemone Nematostella vectensis reveal that the emergence of a core signalling pathway may have been a key innovation enabling the transit...

Ctenophores possess a unique aboral organ that acts as a multisensory center, controlling complex behaviors. We’ve now created a ctenophore model integrated with our 3D volume EM data. Puts it into perspective. Check out our recent work here: www.biorxiv.org/content/10.1... #ctenophores #volumeEM

Calling all #ctenophore researchers and artists! Joe Ryan is organizing the Ctenopalooza Ctwo meeting, which we will host at MBARI in California August 23-25. 🦑🧪🌊 www.mbari.org/event/ctenop... Come swap notes with fellow enthusiasts about the latest news in comb jellies.

Neural connectome of the ctenophore statocyst

Volume EM and connectome reconstruction of the apical organ of a ctenophore combined with high-speed imaging reveals a neuronal coordination of balancer cilia in the gravisensory organ.

#クシクラゲ の平衡器官を構成する900個の細胞のネットワークを３次元的に再構築し、重力センサーの神経回路からその制御機構の謎に迫りました。 重力センサーの動きを高速度カメラで撮影し、その同期・非同期パターンから、これまで謎に包まれていたクシクラゲの神経の機能に焦点を当てています。
