We present an open-access dataset of 10 participants reading words out loud while recorded with intracranial EEG. This data can help in understanding the speech production process better and can be used to test speech BCI algorithms.

We show that imagined speech can be synthesized in real-time and without delay from neural activity.

In this study, we show that decisions are processes differently whether we know what we are deciding about, or whether we are just guessing. Both processes elicit strong enough neural responses that we can decode them from sEEG.

We identified global motor dynamics, that are preditive across tasks and across participants. Even with non-overlapping electrode configurations

Here, we demonstrate that movement-related neural activity can be recorded and decoded from cortical and subcortcial areas throughout the brain.

Can you decode movement from other areas than the motor cortex? Here we decode executed and imagined movement from distributed brain areas using a riemannian classifier.

We created a flexible recording system for neuroscientific research that minimizes setup time and errors, allowing researchers and participants to start experiments easily and independently.

We show that high-quality speech can be synthesized from sEEG recordings using an encoder-decoder framework inspired by Tacotron-2.
