This study shows that speech motor cortex encodes sentence-level linguistic structure and semantic content through single-unit activity in three BrainGate2 participants.

The paper shows that during typing skill acquisition using a BCI, neural population dynamics in the dorsal premotor cortex become more compact, with left hemisphere showing enhanced firing-rate modulation and generalization.

This study analyzes neural activity in the precentral gyrus of two spinal cord injury patients to classify hand gestures with 70% accuracy, showing potential for intracortical BCI applications.

This paper decodes intended speech from a person with anarthria and locked-in syndrome using an intracortical brain-computer interface, showing that phonemes, words, and higher-order language units can be decoded above chance.

The paper measures neural signal instability in long-term intracortical recordings to improve brain-computer interface performance through recalibration timing.
