<p>Scientists have said that if they could add more sounds to the repertoire of brain signals the implant can translate, such systems could be a scientific breakthrough in communication for such patients. <br /><br />Eric Ramsey, 26, has locked-in syndrome, in which people are unable to move a muscle but are fully conscious. <br /><br />“We’re very optimistic that the next patient will be able to say words,” ‘New Scientist’ quoted Frank Guenther, a neuroscientist at Boston University, who led the study, as saying. <br /><br />Guenther said that while a brain implant with invasive surgery could be drastic, but lifting signals directly from neurons may be the only way that locked-in people like Ramsey, or those with advanced forms of ALS, a neurodegenerative disease, will ever be able to communicate quickly and naturally.<br /><br />Devices that use brain signals captured by scalp electrodes are slow, allowing typing on a keyboard at a rate of one to two words per minute. <br /><br />“Our approach has the potential for providing something along the lines of conventional speech as opposed to very slow typing,” said Guenther. <br /><br />His team’s breakthrough was to translate seemingly chaotic firing patterns of neurons into the acoustic “building blocks” that distinguish different vowel sounds.
