Cool new work from @dudman.bsky.social and @fluketc.bsky.social Reward magnitude determines reinforcement learning efficiency: www.science.org/doi/10.1126/...
Standard animal learning studies minimize individual reward magnitudes to maximize the repetitions of reinforced behaviors. We investigated how reward magnitude influences initial learning across five...
Researchers have long searched for the neural circuit underlying locomotion. Now theyβve found it in flies.

New preprint: Whole-body 3D kinematics of freely behaving π·πππ ππβπππ
New tech from @blobology.bsky.social & others at @hhmijanelia.bsky.social, which @ispizua.bsky.social and @elliottabe.bsky.social used to gain insight into 3D structure of locomotion & courtship

A new preprint shows that deep learning can make a fly walk realistically using a wormβs brain β exposing a fundamental problem with how connectome models are being built and sold to investors.

Revision of @sarahpugly.bsky.social's πͺ° walking CPG preprint: www.biorxiv.org/content/10.1...
Major updates:
β motor rhythms replicate across 4 connectomes (incl. 2 new full-CNS datasets)
β robust across all 6 legs
β new analyses of the CPG motif show it's an outlier in the VNC
β improved code docs
for the cpg curious, we made this video to explain the project www.youtube.com/watch?v=twAZ...
The sphinx, with a wormβs brain and a flyβs body, illustrates the potential pitfalls of using deep-learning techniques to model biological processes.
I got to nerd out with @seanmcarroll.bsky.social last week π
Run, donβt walk, to your closest local preprint server to see our latest 3D tracking results!
Iβm still tickled that our results show flies donβt exactly walk, they βground runβ everywhere. I bet they also talk fast and suffer no fools.

1/ New preprint! π§ͺWith @talmo.bsky.social and team, we used deep learning on archival NASA video of mice on the ISS. Turns out mice in microgravity become tiny acrobats: huddling to sleep, doing backflips, even briefly generating their own ~1g. #SpaceBiology #OpenScience #NASA #SLEAP
