Modern neuroscientists routinely record the complex, goal-oriented, and time-varying activity of thousands of neurons. Can we find representations of neural activity that 1) are human-interpretable and 2) enable the generation of neural activity for unrecorded behavioral conditions? We present our recent work on Generating Neural Observations Conditioned on Codes with High Information (GNOCCHI) πŸ₯”πŸ !! By leveraging unsupervised, information-based diffusion models, GNOCCHI can discover interpretable latent spaces from neural data and generate high-quality neural activity for specific conditions outside of the set of available neural recordings!

I started my company originally to build maximally agency-increasing BCI without profit motive, and that's worked decently well so far BUT AGI timelines are shortening, so we are pivoting to work on neglected approaches to alignment

Is a universal brain decoder possible? Can we train a decoding system that easily transfers to new individuals/tasks? Check out our #NeurIPS2023 paper where we show that it’s possible to transfer from a large pretrained model to achieve SOTA 🧠! Link: poyo-brain.github.io/ 🧡

Excited about making models of neural dynamics more interpretable. An ongoing, multi-year project w/efforts led by @arsedle and then @chris_versteeg. Grateful for convos w/@SussilloDavid @MattGolub_Neuro @brody_lab Tim Kim, and our friend @shenoystanford To be continued...
Ever wondered whether the dynamics learned by LFADS-like models could help us understand neural computation? @chethan,@arsedle, @JonathanDMcCart, and I developed ODIN to robustly recover latent dynamical features through the power of injectivity! πŸ“œ 1/ arxiv.org/abs/2309.064021/

lfads-torch also includes recent extensions of LFADS to EMG and 2-photon calcium imaging, and provides a modular interface for experimenting with new reconstruction costs, input priors, and data augmentations. iopscience.iop.org/article/1… nature.com/articles/s41593-0…

This project is the result of a significant engineering effort to make (Auto)LFADS more accessible to the community and we are excited to see how it’s used. Please reach out and let us know what you think!

A wise mentor once helped me understand that this job β€œis all about the people.” I am so proud that these two amazing people are the first PhD graduates from my lab. Congratulations, Feng Zhu and Andrew Sedler!
