This discovery could have a major impact on the quality of life of patients with movement disorders that severely limit or eliminate the ability to verbally communicate, such as amyotrophic lateral sclerosis (ALS) and clinical block syndromes.
Researchers used high-density microelectrocorticographic (μECoG) arrays to record brain activity during a speech production task.
These devices enable highly accurate spatiotemporal measurements of local neural activity, providing significant improvement in speech decoding.
The results showed that the use of high-density µECoG significantly improved the translation of thoughts into speech compared to standard intracranial electroencephalography (IEEG) methods.
