How does the visual system discern eye movements? Visit our poster S04-547 on Monday 2PM to learn from @AnjaSchwartzlose how the visual superior colliculus encodes visual motion and saccade direction in different populations of neurons. #FENS20222 @sylvia_schroed @timothy_sit

Bokeh 2.4 is out! Built-in LaTeX equation support for axes and markups (with more coming), SVG improvements, and a re-written Contributor's Guide all part of @cziscience grant work! Plus many other improvements, read about everything at blog.bokeh.org/bokeh-2-4-6f8…

Replying to @PShamash
@PShamash paper on navigating to goals by learning subgoal locations is now out! Thank you to reviewers and editors for supporting publication of a pure behaviour paper. May this become ever more common. Behaviour is one of the best windows into the brain.
Mice learn multi-step routes by memorizing subgoal locations; new from @PShamash, @trabranco, @SWC_Neuro, and colleagues go.nature.com/3ladsTd

1. Cortical sensory processing is multimodal: visual cortex responds to auditory stimuli, auditory cortex to somatosensory stimuli, and so on. Is there a difference in how cortical populations encode their primary modality vs. other modalities? doi.org/10.1101/2021.07.01.4…

Come for Bayesian GPFA which automatically learns the latent dimensionality of neural data; stay for analyses of multi-region & preparatory activity in 30 minute long recordings from a self-paced reaching task! (with @kao_calvin,@syncrostone,@GJEHennequin) biorxiv.org/content/10.1101/…

1. How does learning affect population codes in visual cortex? We asked this in a new study with @sfailor and @MatteoCarandini. Looking at single cells, the results are perplexing. Looking at populations, they make sense. Now on bioRxiv: doi.org/10.1101/2021.05.23.4…

We introduce a new approach for image compression: instead of storing the pixels in an image, we store the weights of an MLP overfitted to the image 🌟 At low bit-rates this can do better than JPEG! arxiv.org/abs/2103.03123 with @adam_golinski @notmilad @yeewhye @ArnaudDoucet1

I like to think that there are many unexplored applications of space-filling curves, given how cool they look
In case you're into this kind of thing, I wrote a Python package for computing Hilbert space-filling curves with numpy: github.com/PrincetonLIPS/num… It's installable via pip and all that. The implementation is adapted from John Skilling's 2004 "Programming the Hilbert curve".

"Double-dipping" - generating a hypothesis based on your data, and then testing the hypothesis on that same data - is dangerous. To see this, let's take data with no signal at all ... 1/

The eardrums move when the eyes move up, down, and sideways: our latest on eye movement-related eardrum oscillations – what information they carry, and what they might indicate about how vision and hearing operate as partners. A tweeprint! 1/N biorxiv.org/content/10.1101/…

If you missed it on Sunday, my poster about a new technique to study fine inhibitory cell types using spatial transcriptomics is still on this afternoon (poster 649)! With @kennethd_harris @MatteoCarandini @yohisogai #FENS2020poster #FENS2020

Fascinating, identifying a melody just by the movement of the musician? Is this why live performances are so powerful? interestingengineering.com/n…
