Our speech presentation work has now been published in Communications Biology! .Can this be a start to create a more flexible speech BCI based on differential representations of speech and anatomical areas?.

As always, the complete (raw!) dataset is freely available! Check out our preprint, which contains the links to the dataset and code as well: 6/6.

The most accurate and consistent results come from bilateral auditory regions, followed by motor regions ((sub)central sulcus), the supramarginal cortex and parts of the insula. These results highlight the potential of reaching the sulcal depth for speech neuroprostheses! 5/6

Whilst overall slightly lower than in gray matter, we could detect speech with high accuracy in white matter contacts as well. Subcortical areas clearly scored lower than cortical ones, while sulcal regions scored on-par with gyral regions. 4/6

Speech can be detected well above chance for all 30 individuals using all implanted contacts (brain-wide), with much more varied results at the shaft and channel scales, suggesting the potential benefit of sampling multiple regions at once. 3/6.

We decoded speech across a wide variety of intracranially sampled brain regions, tissue types (gray vs white matter), anatomical features (cortical vs subcortical, gyrus vs sulcus) and scales (brain-wide, shaft-specific and channel-specific) in 30 individuals. 2/6

📜New preprint!📜 Speech neuroprosthetic research has focused primarily on the sensorimotor cortical surface, but what if this region is damaged?❌ What are potential alternative areas for speech BCIs?🧠 Let’s explore this!👇 1/6

The motor representation of speech has gotten a lot of attention for speech BCIs lately, but what about non-motor speech representations? How are they all distributed across the brain? We've explored exactly that in our new preprint!

🧠 Learn about stereo-electroencephalography, speech brain-computer interfaces, our open-source dataset, education, how to network, how to handle perfectionism and much more. 🎙 In this podcast episode together with Milena Korostenskaja.👂

Can we still decode movement without an intact motor cortex? 🤔.

A great reminder on our walls everyday to be grateful to all the participants that give us their time and effort to advance science!❤️.
