Congratulations @bentang0 and @zspald11 on your fantastic preprint!
An exciting start for the lab into unsupervised learning and foundation models for speech and language decoding.

A new state-of-the-art neural foundation model.

Excited to announce Pretraining for Sample-Efficient Neural Interfaces, a simple pretraining method for intracranial brain-computer interfaces!

Can a speech BCI learn across people?

In Nature Communications, led by @zspald11:

High-density µECoG reveals shared neural dynamics that can be aligned to improve cross-patient speech decoding, even with little data from a new participant.

How does a speech plan become fluent movement?

In Nature Human Behaviour, led by @dsuseendar:

Intracranial recordings reveal how hierarchical speech plans become continuous motor sequences across planning, articulation, and monitoring networks.

Two new papers from the lab in Nature Human Behaviour and Nature Communications, spanning the neural mechanisms of speech production and new approaches to speech neurotechnology!

🧠 Speech plans → fluent motor sequences

Graphic announcing two new Cogan Lab papers. The Nature Human Behaviour paper asks how the brain turns a speech plan into fluent movement, illustrated as planning → articulation → monitoring. The Nature Communications paper asks whether a speech BCI can learn from other people, illustrated by neural activity from two individuals converging on a shared latent representation.

Last week, Areti Majumdar (2nd year PhD student) presented @jerryptang and colleague’s seminal paper on reconstructing continuous language from non-invasive brain recordings. This 🧵 explores our thoughts and questions.
