A groundbreaking technological advancement has been made in the field of neurocommunication. Two studies published in Nature detail experiments where women, who lost their ability to speak due to ailments like stroke and ALS, were implanted with brain devices. These devices, paired with AI algorithms, allowed the participants to communicate at rates of 60 to 70 words per minute through written words or an avatar. Edward Chang’s team from the University of California created an avatar that not only speaks but expresses emotions like happiness, sadness, and surprise. In contrast, a Stanford-led team implanted devices that recorded signals from individual neurons. Although these prototypes are tethered to bulky systems and are not yet suitable for general home use, they represent a significant leap towards restoring communication for those with speech-impairing conditions.
