MARBLE: interpretable representations of neural population dynamics using geometric deep learning - Nature Methods
MARBLE uses geometric deep learning to map dynamics such as neural activity into a latent representation, which can then be used to decode the neural activity or compare it across systems.

Exciting work by PhD student Zac Spalding @zspald.bsky.social and multiple labs across departments at Duke! A combination of human electrophysiology, modeling/decoding, and cognitive concepts to improve BCI for speech in patients. 👏 🧠📈
We’re happy to present @zspald.bsky.social 's work on shared neural representations of speech production across individuals! We find that patient-specific data can be aligned to a shared space that preserves speech information, enabling cross-patient speech BCIs.
