文摘
- •
Communication rate and accuracy with a P300-based BCI speller did not differ significantly between people severely disabled by ALS who have adequate vision and age-matched control subjects.
- •
The two groups differed significantly in P300 amplitude and location, N200 amplitude, and latency of the late negativity (LN).
- •
P300-based BCI studies and usage in people with ALS may benefit from use of additional ERP components and alternative montages.
