Last week, Zac Spalding (@zspald.bsky.social‬, 4th year PhD student, @dukeubme.bsky.social‬) presented Adam Gosztolai, Robert Peach, and colleagues’ 2025 paper on MARBLE, a method for finding interpretable latent representations of neural dynamics.

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. 👏 🧠📈

From Cogan Lab Journal Club with @zspald.bsky.social these decomposition acronyms are getting out of hand!

Excellent work by @zspald.bsky.social !! He finds that a shared neural speech production space across Micro-ECoG patients boosts decoding performance. Check it out! @dukebrain.bsky.social @dukemedschool.bsky.social
