Our first preprint has been accepted for publication www.science.org/doi/10.1126/... !!
tldr: @ezeyulu00.bsky.social , @amartyapradhan.bsky.social , @dkoveal.bsky.social and I developed a method using injectable nanoparticles to turn mice into…constellations in motion. 🧵⤵️

High-resolution in vivo kinematic tracking with customized injectable fluorescent nanoparticles

Injectable fluorescent nanoparticles were used to track positions on and inside of freely moving animals at high resolution.

Congrats, Jeff! I can’t wait to try it out

Sabbatical question - which activities do you keep up and which do you pause?

Eg reviewing new papers and grants, non-mentorship related service committee meetings, normal schedule of lab meetings…

Ariel Levine @ariellevine.bsky.social · 27d

Yes I hope so! And thanks :)

Do you know of a third color that can be added to cyan and orange and for which the paired with overlaps are different? Thank you!

1

Ariel Levine @ariellevine.bsky.social · 27d

Agreed! But do any of these work for 3 color overlap analysis on a black background? For example, in RGB, we’d want to distinguish between R+G yellow vs R+B purple. But make it colorblind friendly

Does anyone have favorite colors for color blind friendly fluorescence images on a black background where the overlap combinations of 3 colors are important?

Magenta/cyan/yellow overlaps are difficult to distinguish (lots of white)

Thank you!

Excited to share my latest work with @jonathanamichaels.bsky.social @diedrichsenjorn.bsky.social & @andpru.bsky.social!
We asked: How does the motor cortex account for arm posture when generating movement?
Paper 👉 www.biorxiv.org/content/10.1...
1/10

Compositional neural dynamics during reaching

The complex mechanics of the arm make the neural control of reaching inherently posture dependent. Because previous reaching studies confound reach direction with final posture, it remains unknown how...

Cool! Yes I saw the one walking task but wished for more ;) also, re posture, I meant to include it as a background context for other behaviors/tasks (a conducive/natural posture vs arbitrary/atypical)

Anyway, I’m really intrigued to see how this develops!

Ariel Levine @ariellevine.bsky.social · Sep 4

Also very curious about modeling of an overall “postural” component and more whole body/lower limb driven behaviors

Ariel Levine @ariellevine.bsky.social · Sep 4

Congrats! It’s a little far from my wheelhouse but this seems like a fantastic way to approach the “problem”.

Is there a way to build up a layered model that mimics vertebrate evolution to see if that improves finding more universal (vs task specific) representation?

How do neural dynamics in motor cortex interact with those in subcortical networks to flexibly control movement? I’m beyond thrilled to share our work on this problem, led by Eric Kirk @eric-kirk.bsky.social with help from Kangjia Cai!

Despite some ups and downs at NIH, we do have an open position for a postbac and are considering candidates.
Our work is at the intersection of neuroscience and AI, and we aim to understand how the brain's densely connected recurrent networks operate. 🧪

Well, turns out that’s just how they did it way back when. Fritsch and Hitzig in 1870 through at least some 1906 Sherrington
