Learning-related population dynamics in right and left dorsal premotor cortex during typing skill acquisition

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.

Gesture encoding in human left precentral gyrus neuronal ensembles

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.

Decoding intended speech with an intracortical brain-computer interface in a person with longstanding anarthria and locked-in syndrome

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.

Measuring instability in chronic human intracortical neural recordings towards stable, long-term brain-computer interfaces

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