Decoding speech from intracortical multielectrode arrays in dorsal motor cortex
The team detected speech-related neural activity from the same Utah arrays already placed in the dorsal “arm/hand” area of motor cortex of an intracortical BCI clinical trial participant with tetraplegia. This enabled us
to study the motor cortical dynamics during speech production at the unprecedented resolution of populations of single neurons, and to prototype classifying between 9 spoken syllables with 84.6% accuracy and between 10
words with 83.5% accuracy.
