How do 🐁deal with complex landscapes? Turns out they learn a lot very quickly. We think they do this by learning a set of repeated sparse paths, which form a type of compressed world model. Joint work with the Hermundstad lab, led by Tzuhsuan Ma and Alison Comrie: www.biorxiv.org/content/10.6...

Butterflies and axolotls: our acquisition systems had a busy summer at the MBL @mblscience.bsky.social ! 🦋🧠 This year, we supported Grass Fellow Jack Supple and Whitman Fellow Angelo Forli @aforli89.bsky.social with Open Ephys acquisition boards. Here’s what they’ve been up to.

Jack recorded from the butterfly ventral nerve cord during visual stimulation. Using multiple headstages simultaneously was especially useful.

Angelo got the first ‘modern’ ephys recording from the brain of an axolotl! He said: “Many thanks to Open Ephys for making the acquisition setup so simple and yet powerful, so I could focus on the experiment.” Glad we could help, and thanks for sharing your summer science with us!
