Sehr interessanter Artikel auf Telepolis<\/a>: „Gedankenlesen ist keine Science-Fiction mehr. Durchbruch bei Gehirn-Computer-Schnittstellen: Forscher gelingt es erstmals, Gedanken direkt in Sprache zu \u00fcbersetzen \u2013 ganz ohne Sprechen.“<\/p>\n

Source EurekAlert<\/a>: „Scientists have pinpointed brain activity related to inner speech – the silent monologue in people\u2019s heads – and successfully decoded it on command with up to 74% accuracy“ sowie die Original-Forschungsergebnisse<\/a> „Inner speech in motor cortex and implications for speech neuroprostheses“.<\/p>\n

Speech brain-computer interfaces (BCIs) show promise in restoring communication to people with paralysis but have also prompted discussions regarding their potential to decode private inner speech. Separately, inner speech may be a way to bypass the current approach of requiring speech BCI users to physically attempt speech, which is fatiguing and can slow communication. Using multi-unit recordings from four participants, we found that inner speech is robustly represented in the motor cortex and that imagined sentences can be decoded in real time. The representation of inner speech was highly correlated with attempted speech, though we also identified a neural \u201cmotor-intent\u201d dimension that differentiates the two. We investigated the possibility of decoding private inner speech and found that some aspects of free-form inner speech could be decoded during sequence recall and counting tasks. Finally, we demonstrate high-fidelity strategies that prevent speech BCIs from unintentionally decoding private inner speech.<\/i><\/p>\n
