  EEG study finds the brain can encode two speech streams at once during attention switches

  Researchers used EEG in a multi-speaker listening task to study how people switch attention between competing speech streams. The results suggest a brief overlap in neural tracking, where the new target stream is encoded before the old one fully disengages, alongside changes in alpha power and lexical-context updating.

  Meta Open-Sources Brain2Qwerty V2 for Noninvasive Brain-to-Text Decoding

  Meta has open-sourced Brain2Qwerty v2, a noninvasive brain-computer interface that decodes sentences from EEG or MEG brain signals. In reported evaluations, it reached 61% average word accuracy, substantially outperforming other noninvasive approaches at 8%.

  Meta shows non-surgical brain-to-text decoding

  Meta reports a research system that can decode brain activity into words and typed text without requiring surgery. The work suggests a potential communication aid for people with severe speech impairment, but it remains a laboratory research result rather than a consumer product.
